Welcome @Spookweave 
The version of Proton you use on a per-game basis may be quite important. If your default in Steam is to use the latest, which is not unusual and generally ok, an update may seemingly break games that were previously working.
So for some games, it’s necessary to specify an older version of Proton. Figuring this out is largely a process of trial and error, rolling back the version till you hopefully achieve stable game play. You can also refer to community tips on ProtonDB, for what has worked for others.
I’d also recommend trying Proton GloriousEggroll (typically named ProtonGE) and perhaps leaning on that as your default Proton version. You can install that from the AUR as proton-ge-custom-bin.
Lastly, your integrated Intel GPU is far from being a gaming GPU, so expectations will need to remain tempered. It’s roughly the equivalent of a 15 year old Nvidia GPU (eg: Nvidia GTX 560).
