If you are like me and none of the "fixes" worked for you and lord knows I tried everything, try the following and let me know if it works.
So I found a fix that worked for me after trying EVERYTHING!
Step 1. Close steam
Step 2. Goto C:\Program Files (x86)\Steam\steamapps\common\Baldurs Gate 3\Data
Remove the following files: Patch1.pak, Patch0_Hotfix3.pak and Patch0_Hotfix4.pak (I put them in a seperate folder on the desktop in case I need them)
Step 3. Goto C:\Program Files (x86)\Steam\steamapps\common\Baldurs Gate 3\bin
Run the bg3 exe file as admin.
I went from crashing every 10 mins to playing over an hour now without a crash. I did this methodically by starting with Patch1, still crashed, patch hotfix3, still crashed when I removed 4 it stopped crashing. Now I have not tried it but the game may run fine with Patch and Hotfix 3, just not 4 but I have not tried this yet.
All hail The Absolute!
