Question FIFA 21 glitching and crashing & other games simply crashing ?

[inpain]

From what I found on the internet, these errors seem to be related to controllers on pc but I'm using keyboard and mouse only.
Since yesterday, I whenever I try to play FIFA 21, the game glitches on the kit selection screen and an error (https://ibb.co/1qLNQz2) pops up crashing the game. If I manage to get past the kit selection screen, it gives me another but similar error (https://ibb.co/qC6mMyM). I tried playing RDR2 and there's just black screen after loading is complete and I can only hear the audio (birds, etc) but no display and when I touch the movement keys, the game crashes with this error (https://ibb.co/pdTYr8D). Similarly, Forza Horizon 5 crashes while loading (without any error dialog).

Things I tried:

1. Changed the dx_select from 0 to 1 using notepad in Documents > FIFA 21 > fifasetup.ini
2. Disabled full screen optimizations of FIFA.exe from properties
3. Made sure I had latest drivers in GeForce Experience
4. Physically removed and re-inserted the graphics card

Any help is much appreciated. Thank you.

Thanks for suggesting. It is Cooler Master 230V MWE 550. This pc was built in 2019 if it helps. I have edited my post to add these points. I have never faced any problems playing any games since 2019. It all occured suddenly.
