Okay so I have been having an issue where, when I try to start Crusader Kings 3, the game fails to launch. No error code or any just, Launching the game Failed. It's in the latest version(1.3.1 Corvus). I've tried uninstall reinstall, off and on, the works. this has been happening since yesterday and i can't play with my friends. I would love some help here. Playing on Windows 10 using Steam.

In the game launcher please set Display mode to windowed.

IF that doesn't help, 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/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 your Documents/Paradox/CK3/pdx_settings.txt .
From your Documents/Paradox/CK3/logs/ folder, attach system.log , error.log
