Please do a full **clean** re-install:

- move any valued save games elsewhere
- "uninstall" in Steam-CK3
- manually delete both the Steam/SteamApps/common/CK3 AND Documents/Paradox Interactive/CK3 folders
- re-install game in Steam, run a Steam Verify when done.
- add CK3.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.
- start the game with no mods active and test

In particular make sure there are no files or folders left under either the Steam CK3 or Documents CK3 locations, before installing again.


If those don't help:
DXDIAG is a program you run from the Windows search box on the task bar. 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.

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

I think we may have a problem with this unusual Windows version:
Windows 10 IoT Корпоративная LTSC 64-bit
I don't recall seeing it before, but this is the third one this week! From what i see it's not intended as a consumer OS but for hospitals etc, and in any case is due to leave MS support this month. And I'm pretty sure our games are not tested on it at all.

Do you have access to a normal consumer build of Windows 10 or 11 you can move to?


Meantime, 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.

Is that any better?

A case here where swapping to a standard Windows version helped

Game crash upon startup after graphics card update

I recently updated my graphics card (nothing out of the ordinary, just a pretty standard update), and now CK3 is unable to start up. Every time I click "play" on the game launcher, the game will attempt to launch, but then crash quickly after. I... forum.paradoxplaza.com forum.paradoxplaza.com
