[2022] Game launch issue (C++, DotNet0

toverjong said: I just bought the game and am experiencing the same issues the non AVX processor guys were having this summer. However, I have a fairly recent processor with AVX2 and am still experiencing the issue

In that case you have an unrelated problem, as that bug is definitely fixed now.

We see no crashes in ck3.exe in that dxdiag.

Right click on ck3.exe , properties, compatibility. Tick "disable fullScreen optimisations" untick every other box in that dialog, Apply and exit.
Then in the launcher Game Settings menu, select fullScreen display mode, Vsync off, refresh rate 60.

IF that doesn't help, run ck3.exe directly from file explorer - what happens? Any error show then?

Please attach here your Documents/Paradox Interactive/CK3/pdx_settings.txt .
From your Documents/Paradox Interactive/CK3/logs/ folder, attach here system.log , error.log , exceptions.log  

System file corruption – System file corruption is probably the most common cause that will trigger the 0xc0150004 error code
