Spiral screw extractor — go slow. Your only other option is really to just fill it in with some color matched wood putty and have the hinges be in a separate location (this will depend on the extent of your refit).
Ez out this looks like a decent candidate for it to work
You can try predrilling a small hole in the screw shaft and use a small easy-out extractor, otherwise you'll have to drill them out, they are aluminum screws and the only reason they used aluminum was so they could anodize them red, terrible design choice, you have to be so careful and use the proper sized Phillips bit to get them out, once they strip a little, its game over.
You can get screw/bolt extractor bits/kits.
You drill a hole in the broken bolt, and then insert the tapered extractor and start screwing it into the hole. As you screw it in and it gets purchase, it starts to screw the broken bolt out. If the thread proves to be stubborn once the bit is firmly in I find the hammer setting on a drill or impact wrench helps budge it.
An example of a screw extractor is this:
There are screw extractors available that’ll take that out in second. They’ve saved my behind more than once.
Best bet is to go with an extractor set IRWIN Screw Extractor for Spiral... https://www.amazon.com/dp/B00004YOBF?ref=ppx_pop_mob_ap_share. These are the ones I use at work they do a well enough job but any brand works about the same. Not sure if you have used any before but if you haven't what you want to do is first see if the hole is big enough already to get a decent bite with the extractor if not you need to drill it out a bit more. Tap it in with a hammer so it is in there snug then use a wrench or pliers to slowly turn it out you do not want to hook the extractor up to your drill.

These screw extractors are too big but you get the idea. I'd try the other ideas first and then a screw extractor.. Try to prevent metal chips from getting in the controls.
This looks like a Price Pfister? Under that handle will be a plastic spindle with metal pin that screws in to the plastic that has an indention where the hex screw rides (stripped hex screw in this case). I would give it a little penetrating oil and use an screw extractor to slowly back it out.
Hopefully it doesn't get to that point, because if it snaps, you may be able to tap it off-center with a flat head screwdriver in hopes it starts working free, or drill it and buy some of these to get the rest out.
And yeah, I imagine kroil would never hurt if it's stubborn.
To expand on what others have said. The bolt nearly broke inside what it was fastening. If the bolt had broke it's a very difficult process to remove the rest of the bolt and requires left hand drill bits, a steady hand, maybe a bolt extractor, and luck. When drilling the bolt out you have to make sure you don't damage the threads of what the bolt is inside of.

Even grabbing the d-ring with pliers isn't working? Worse case scenario just pick up some screw extractors while you're at the hardware store. You'd need a drill and bit too to start a hole for those to grab into.
It's too late now, but last time I had a very very well seized thru-axle even the LBS wasn't able or willing to get out, I eventually managed to extract it with one of these types of easy-out and a nice big wrench on the end. Took a heck of a lot of leverage and made some nasty noises, but came out without damaging anything other than the axle.
I have used screw extractors in the past with similar issues. I have a set like this in my tool bag. Amazon Link
Remove the hot end and then use this
Try not to damage the hot end.
If it doesnt work you'll have to replace the heater block
I've used a screw extractor to do this. You can find them at hardware stores, and here's what they look like on Amazon. To do this, you'll need to carefully drill a hole down the middle of the stuck bolt but not as deep (so you don't drill into whatever is at the end of the bolt. The size of the hold will depend on the bolt size and the size of the extractor. It probably wouldn't hurt to apply rust remover to the bolt before you begin.
​
Once you've finished drilling, tap the tip of the screw extractor into the drilled hole, and then turn it counterclockwise using a screwdriver bit holder or locking vise-grip pliers. The extractor has threads that will pull it into the hole, and it should eventually engage enough to unscrew the bolt.
A screw extractor may work. If you go that route, use a tap wrench (or similar) and not a power tool. The extractor bits are hardened and will snap if they're mishandled.
Also, check the quality of your screwdriver head and verify it's the proper size for future use. If the head looks chewed up buy a new one and save it as a PC stuffs screwdriver.
As in not locally owned, or as in not near your home? Amazon has these that work nicely.
That remaining bolt tightens into that little extension piece. See if you can remove that one, pull out that extension piece, and you should be able to see the other end of those broken bolts. I'd pull mine off and take a picture for you, but the bolt for that extension piece is one of the bolts holding my aftermarket bumper on, and I really don't want to mess with that right now. Those two bolts you broke off are two I never reinstalled, so they're open holes that look like they're just nuts welded into the frame member.
Either take it to a local tire shop and give them a few bucks, or torch + easy out (or equivalent, like these: https://www.amazon.com/Irwin-Industrial-Tools-53535-Extractor/dp/B00004YOBF)
If it's bottomed out on the threads or the blind hole and torqued down, the only things that will work are extreme that most can't do. Mill the whole thing out. Or mig weld a bar to the top of the fastener.
If it's not torqued down you might be able to center punch it, use a hand drill to drill a small hole in the center then use a screw extractor.
Buy a cheap set of screw extractors. https://www.amazon.com/dp/B00004YOBF
Nice!
I like my discount ali cars, but the screws are garbage, I replace every one I pull out. I recommend these two things I've bought myself.
Screw extractor set (do by hand with pliers or a handle like from a "tap and die" set). https://www.amazon.com/gp/product/B00004YOBF/
304 stainless steel screws (smaller sizes, first is recessed, second button head).

Get a grinder and cut a slot in it. Use a flathead screwdriver to take it out. Or buy a set of these
https://www.amazon.com/Irwin-Industrial-Tools-53535-Extractor/dp/B00004YOBF That's the link for the set. The small one might work as is. If it doesn't grab though use a 5/64 drill bit and drill a little bit deeper.
You could use a screw extractor bit if you don't mind putting a small hole down the center? Something like this is what I would use. Then epoxy the nub back to the stand.

For the future, these work for hex heads too:
Get some bolt extractors. (https://www.amazon.com/Irwin-Industrial-Tools-53535-Extractor/dp/B00004YOBF)
Drill out the center (might work on the existing hole), hit the surrounding metal with a torch, and use the extractor.
I want to make sure we’re taking about the same thing. At 3:30 in this video , he’s pointing at the round bushing installed on the car. That bolt is the one I broke the head off of once. I wouldn’t think you’d harm the bushing doing that but you will have to get the bolt out. I was able to drill a hole in the middle of the bolt and use a kit like this to get it out. It’s a pain because you’re on your back the whole time.
If I misunderstood your situation, let me know.

I don't know what's available in Singapore, but there are drill bits made for removing screws like this. Loads of companies make them and they are widely available, so I'm sure you can find something.

Easy Out.
Personally, if not a problem I would worry about it.
Use a screw extractor along with penetrating fluid and possibly heat if needed.
Should be able to jam a screwdriver in there. Heating it up might help too. If it's really fucked in there then you might have to remove the block and use an extractor. You could just carefully drill it open and use something like these https://www.amazon.com/Irwin-Industrial-Tools-53535-Extractor/dp/B00004YOBF/ref=sr_1_3?crid=3JHXH92W504VE&keywords=easy+outs+extractor+sets&qid=1642901047&sprefix=easy+outs%2Caps%2C76&sr=8-3
The brass is going to pull on the drill and might even come out buy drilling it. Because of this tendency machinists will modify the drill a bit. Basically you grind a negative rake on it but, it looks like this https://handycrowd.com/drilling-brass-the-easy-and-safe-way/. You definitely want to be careful while doing this and a drill press and vise is extremely advised or you may drill through your whole block before you even know what happened.
Use a screw extractor such as this one, Irwin.
err... they made far better and correct tools for that, as other posters have mentioned

They are M8 X 1.25, 45 mm long. You can use a screw extractor to remove the broken bolt.
Honestly, you can get the job done with being a bit more diligent with your selection.

That has a bit of head on it, you might be able to get a dremel and flatted it enough to just get the vice grips on it. If not you can use some extractors:

Screw extractors work great for removing them. You can get yourself a nice torque wrench while you're at it ;)

You might be able to get it with an ez-out / screw extractor, otherwise it looks like it might be time to drill off the screw head. If you need to drill it out, use a bit that's slightly smaller than the head of the screw and stop as soon as the head is removed. That way you'll leave enough of the screw exposed with the cover removed that you can get a hold of it using a vice-grip pliers.
You should be able to find an extractor at a local auto parts store or tool store, otherwise Amazon has a multi-pack that should work: https://www.amazon.com/Irwin-Industrial-Tools-53535-Extractor/dp/B00004YOBF
You could try one of the screw remover drill bits if you've got a drill to use. Like these screw extractors for example?
You need to run down and get a set of eazy outs, I dont know what size exactly the tip needs to fit into the nozzle a little bit. Something like this https://smile.amazon.com/Irwin-Industrial-Tools-53535-Extractor/dp/B00004YOBF/ref=sr_1_6?ie=UTF8&qid=1518050826&sr=8-6&keywords=easy+out OR https://smile.amazon.com/Extractor-Hardness-Stripped-Removers-Jelbo/dp/B06XT3S7CJ/ref=sr_1_1_sspa?ie=UTF8&qid=1518050826&sr=8-1-spons&keywords=easy+out&psc=1&smid=A2O3U707GC6UX7
Follow the instructions on the tool for extraction of the screw
But BEFORE you try to take it out, you need to heat up the nozzle to at LEAST 235-240. Then try to remove, following the instructions
