[2021] Another Game Crashing on Launch Thread

Your launcher is fairly old, so lets update that . Please try this:

- exit the Steam app entirely
- uninstall Paradox Launcher v2 from the Windows "Apps and features" utility, if still present.

Delete the following folders if still present:

- C:/users//AppData/Local/Programs/Paradox Interactive/
- C:/users//AppData/Local/Paradox Interactive/
- C:/users//AppData/Roaming/Paradox Interactive/launcher-v2/
To see the AppData folder you'll need to enable View Hidden Items in File Explorer.

- run steam.exe as the Windows Admin user

- run the game from the PLAY button in Steam

IF that doesn't help, in this folder are some .log files:
C:/users//AppData/Local/Paradox Interactive/launcher-v2/
Please attach them here.


As for the game, it fails running from ck3.exe directly, is that right? We see many GPU errors in that error log, so let's check that out:
DXDIAG is a program you run from a command prompt or the Windows start menu 'run' dialog box (or 'search programs' in Windows 7 or later). After running it will open a window and start collecting info with a progress bar in the lower-left corner. When it completes click the 'save all information' button and save it to a file then attach that file here.  

That first screenshot shows an older launcher version still, 2020.14 . Yet i see the current one 2021.1 downloading in cpatch.log. Is there an orange or red dot up the top left of the launcher?


As for the game, what happens if you exit the Steam app entirely then run ck3.exe directly from Windows Explorer? Any Windows error show then?  

That's a link to this same thread ...

Looking back at your dxdiag I see tha AMD video driver is from 2015. Please try the current one:

Good luck!
