Sadly, this doesn't work for me either. Since the "hotfix" my game is constantly crashing at startup. Something about ntdll.dll in the event log. Vulkan and dx11, run as admin, rename the folder, none of that worked. I tried reinstalling the game and that didn't work. I've got almost 70 hours in the game so far so it USED to work. I'm not sure what to try next. Nvidia graphics drivers also updated at the same time. Maybe try rolling them back. Not sure.
I figured out a workaround. If I kill all the Steam processes in task manager and then launch the game as administrator from bg3.exe then it will run as expected.
