Quick update. Ran the game through steam with this launch option:
"C:\Program Files (x86)\Steam\steamapps\common\Baldurs Gate 3\bin\bg3_dx11.exe" %command%
which just launches the game without the launcher. Seems to have fixed it for me, at least today. 6 hours of play, no crashes. I did try running both game executables direclty as admin, both immediately crashed. No idea why.
Hopefully that's helpful to some of you.
