BF6 constantly crashing and now other games having same issue

I bought bf6 a few days ago and it was running fine until it stared getting the direct x error and crashing. I tried all solutions I could find online to fix this but nothing worked. I then tried playing other games on my pc which have had absolutely no problems until now and they are crashing too. GTA 5 enhanced, KCD2 and Crimson desert are all now crashing after a maximum of around 5 minutes gameplay. This game has effectively broken my PC. I have done a full factory reset to try and wipe any corrupted direct x files but this has made no difference.

Please can you help me fix this as it has rendered my gaming PC useless for gaming. 

Running: Ryzen 7 7700, 16GB RAM, RTX 4060 Ti
