Same issues, I share your pain buddy
I'll copy my post from another thread to give the issue a little more visibility.
Might help if you include your own system specs and steps taken. Larian does seem to read this forum.
Also experiencing a ton of crashing, since the aug 26th update. It actually seems to have gotten worse after one of the hotfixes. They are all crashes to desktop, displaying a Vulkan or DX11 error depending on which one I'm using. No discernable pattern in what causes the crash - it can happen in a tiny area, the open world, in and out of combat.
Fixes tried so far:
verifying steam installation
switching between DX11 and Vulkan
changing in-game settings (DLSS, AO, borderless, etc)
updating graphics drivers
skipping the launcher as mentioned previously
blowing out dust and checking that gpu/cpu temps are within norms while playing
Performance is quite good, except for occasionally encountering some strange stuttering in npc heavy areas. Like it can get real bad in Last Light Inn one day, and then be buttery smooth the next. Lowering settings doesn't seem to change that, even shaders and light sources.
