GPU keeps timing out and I've tried just about everything I can think of

Hey there @Misology_1! Welcome to the community! I’ve noticed an increase in AMD GPU timeouts and crashes lately. Some users have been getting relief from disabling Adrenalin/MSI afterburner, though this isn’t a magic bullet. Often it’s crashes instead of timeouts. I’m assuming your reinstall of the drivers defaulted your settings, but if not that’d be my next recommendation.

Does this occur immediately on launch or after some use?

This response I’ve made before helps many graphical issues of this nature, though is more geared towards Nvidia users so you may need to adjust the recommendations a bit.
