Game unable to launch since update 1.14.3 [null exit code]

[Archicuse82]

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

Hello. Even with the 1.15 update, I still have the null exit code.
I attached here some documents, and I don't understand what's the reason of my not-working launcher (because my game works when I run the .exe, but no in the laucher).

I moved you into your own thread, as your issue is unrelated to the topic of the thread you posted in. Please always start a new thread in future, thanks.

Game logs cannot tell us why the launcher cannot start the game I'm afraid.
in this folder are some .log files:
C:/users/{userName}/AppData/Local/Paradox Interactive/launcher-v2/
Please attach them here.
To see the AppData folder you'll need to enable View Hidden Items in File Explorer.

Thanks for your response, and I attach files which are in the folder "log".

No clues in there!

The most common cause of this game failing to start since the recent 1.14.3 patch is Avast, Norton's, Sophos or AVG antivirus (at least!) blocking the updated ck3.exe . Regardless of what AV app you use, make sure ck3.exe is in all its exceptions lists.
