They sell one handed keyboards. In your case, there's an Intel Remote Keyboard app for phones that works on Windows. That may be the most comfortable. Android version: https://play.google.com/store/apps/details?id=com.intel.remotekeyboard
It says it's for compute sticks but supposedly it works on any Windows PC.
Your keyboard probably has a loose connection or a short somewhere. I think you have asus zenbook based on that partial model number. Try connecting a external keyboard if you have one. If you dont based on that partial model number you should have a intel chip which in compatible with intel remote keyboard which you can download here. https://play.google.com/store/apps/details?id=com.intel.remotekeyboard&hl=en
