[2023] Game crashes on launch on PC

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.


Does that make any difference?  

I don'ty see any other known cause in those files. What if you make a new WIndows user and log in with that - does the same problem happen?

I promise you, signing up for the crown did not cause this to you. If it did we'd have thousands of such reports.

What did, I simply cannot see.

Do you have access to any other computer you can do a test install on? That will tell if it is confined to this one machine, or perhaps and account or MS back-end problem.  

It shouldn't be, but not impossible I suppose. We have a thread on that here:

Crash on startup (fresh W11 install + no mods) - Xbox PC app

Since 1,5 weeks, I am unable to start the game. I was just playing when it suddenly crashed. Since then, I have not managed to get passed the fiurst loading screen anymore. After starting through Xbox app and then the CK3 launcher, I see the main... forum.paradoxplaza.com
Basically those saves are in the MS cloud and we have no access to them. Nor do users, aside from via the game as far as we know!  

I did escalate it to my manager who took it to the game's developers. I don't know what happened from that point I'm afraid! I can ask again next week (yet another Swedish public holiday today).

Have you raised it with MS? It is always best to attack such issues from both ends, IME.  

I'm not suggesting that MS make previous game save file compatible with the latest game version. We don't even know that is the problem here, it may be corrupted save files.

What we want from MS is a way to at least see your files in their cloud outside the game (as is possible with Steam), and a way to delete them OR they delete them on request.  

Has anyone had any luck in contacting MS on this issue, of cloud save access?
