Also In my opinion, another potential fix is to boot into Safe Mode, uninstall all NVIDIA updates, and then restart your PC. After that, avoid reinstalling any NVIDIA drivers. This method worked for me, and I've been able to play games like Valorant, PUBG PC, CS:GO, and Death Stranding with only minor fluctuations, but no BSODs or crashes.
