Has it always happened with this game since you've had it? Or only since when?

We see some GPU/driver issues in that error log, so you might try a clean reinstall of an older driver:

- uninstall the existing one with this tool:
https://support.amd.com/en-us/kb-articles/Pages/AMD-Clean-Uninstall-Utility.aspx - reboot
- install the one from May 2020 from here:
http://support.amd.com/en-us/download - reboot again

Good luck with that!

I suggested the May 2020 driver version for a reason, as the last known good one - can I ask you to do that clean reinstall again but use that one?

No crashes in the game recorded in that dxdiag, interestingly.
Blazadin said: Reinstalled game via Gamepass, mashed ESC while loading launcher and continued to mash escape as the game loaded. Got it to work again.
That sounds like the old wsg fix for gamepass ... I assume the Steam copy still fails?

Exit the Steam app entirely then run ck3.exe directly from Windows Explorer - what happens then? Any Windows error shown?
