getting DXGI_ERROR_DEVICE_REMOVED in a flight sim, and now in a second game too, which makes me think it's 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 Radeon Adrenalin Graphics Driver from AMD, crashes started the same night. i tried rolling back but now Windows Update keeps reinstalling smth 🤦 Im starting to feel like Im fighting my own PC. Whats the proper way to test this? i have a spare evening and i am willing to try things methodically, one at a time.
