Game launches incorrectly. Goes to main menu, but cannot click on anything.

[DreadLindwyrm]

I am having problems launching CK3.

When I attempt to launch the game, the launcher comes up, and then when I click to launch the game it goes through the loading screens to the main menu.

I then do not have a cursor, or the ability to click on anything.

I have tried verifying files, rebooting my machine, but to no avail.

Launcher version 2025.3

Launching with no mods shows me version Crown (1.15.0) checksum 1d66

Additionally to this :

It appears that my computer doesn't want to acknowledge the screen that the game is running on, as when I try to move my cursor onto it, and then move it back it's as if the cursor isn't moving on the game screen as it instantly returns to my second monitor rather than taking the time it *should* take to move across the game screen before reappearing.

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

- move any valued save games elsewhere
- "uninstall" in Steam-CK3
- manually delete both the Steam/SteamApps/common/Crusader Kings 3 AND Documents/Paradox Interactive/Crusader Kings III/ folders - In particular make sure there are no files or folders left under either the Steam CK3 or Documents CK3 locations, before installing again.
- 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.

THEN 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, cap refresh rate at 60.





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.


IF dxdiag.txt fails to attach here, rename it to dxdiag.log , or zip it up.





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.txt

Sorry, I forgot to close this.

I solved it by switching renderer to Vulcan and (weirdly) changing it from my main screen to the secondary one and back.

Thanks for the response though, and I'll bear it in mind if the problem reoccurs.
