Hello. I spent months trying all the above to fix the random dx11 error crashes. Went even as far to do a full factory reset on my entire computer, deleting everything (which did not work).

What finally worked for me was replacing my CPU (Intel® Core™ i9 processor 14900KF) with a new one (Intel® Core™ i7 processor 14700K).

Have not crashed since, and it's been a week! I hope this helps those out there who might be at their wits end.

Cheers,
Ossi
