Sorry for not getting around to replying sooner. I've tried disabling the Steam & Nvidia overlays (meant to also disable Discord, but didn't), an sfc /scannow command, and reinstalling the game on my C drive. I did upgrade to Windows 11 in October, but I'm pretty sure I had a couple of crashes before that. Also, yes, I have updated my drivers to the latest Nvidia drivers that have been released since I initially created this thread.
