Yes. Replace the breaker with a 15 amp and install an outlet using wire nuts and some short pigtails. This way if you ever had to swap it back it would be very easily done. You can always use wire larger than it needs to be, just not smaller. Pigtails may be required at either or both ends.
You can also purchase these if you want a more turn key solution. https://www.amazon.com/dp/B07CJ246JP/ref=cm_sw_r_cp_apa_i_DQZtFbCG68GQC

Southwire 9042SW8801 UL Listed Electrical Outlet Gas Range Adapter
You can do two things. Replace the outlet with a 120v receptacle. All you need to do is drop a phase.
Or you can buy a adapter. https://www.amazon.com/Southwire-9042SW8801-Outlet-Range-Adapter/dp/B07CJ246JP
It’s a Southwire adapter. Seemed legit:

This is an adapter to convert the 220v to 110v. The US uses split phase 220v and our 110v outlets are (over simplification warning) only using half. If you want to learn more watch this.
I don’t own a multimeter yet, but just ordered one. What would cause the over voltage? The workmanship from the previous owner was pretty bad in other areas, but shouldn’t the adapter be stepping it down?
Here’s a link to the adapter: https://www.amazon.com/dp/B07CJ246JP/ref=cm_sw_r_cp_api_glt_fabc_VKD5Y69E650PET9KP65E
