Vulkan is inherently unstable for the game right now, moreso for Nvidia cards. Some people (most notably those with ATI cards) see more stability/gains from it. Some people aren't able to run with Vulkan at all.

I chose not to use Vulkan due to instabilities. I'd rather have a solid game experience and not worry about it crashing at a critical moment (or during a save).

You could try the studio drivers from Nvidia if you wanted. Or you can try uninstalling the Nvidia driver you currently have, booting into Safe Mode and using DDU to do a "clean wipe" of driver residue, and then downloading/installing a fresh copy of the driver your card needs.
