help!! getting DXGI_ERROR_DEVICE_REMOVED in a competitive shooter, and now in a second game too, which makes me think its not a game problem.

Fatal error
The game has crashed and will now close.
DXGI_ERROR_DEVICE_REMOVED
The GPU device instance has been suspended.
timeline: installed Catalyst Display Driver from AMD, crashes started the same night. I tried rolling back but now Windows Update keeps reinstalling smth. I'm starting to feel like I'm fighting my own PC, what's the proper way to test this? lmao I have a spare evening and I am willing to try things methodically, one at a time.
