[2022] Cant Play the Game (Not Responding)

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?  

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  

That error log looks like before. Did you move the saved games out when you did your clean reinstall before?

If not let's try again:

- 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.  

A much better error.log but still no clues as to what is causing this to you.

Please report the temperatures of your CPU and video (GPU)
1/ before starting the game up and
2/ after say 10 minutes' play.
If your PC's vendor has given you no way of reading temperatures, install

Really not sure what else to look into here. Has this problem always happened on this machine? Or it was okay up to some point?

What if you make a new Windows user and log into Windows as that? Does the same problem happen then?

I'm about out of ammo on this one. I cannot see what is wrong in Windows or your machine to cause this to you.

I suspect a clean wipe and reinstall of Windows would fix it, but that's a lot to contemplate to get a game going, I know!

When these freezes happen, is it just the game or the whole machine? Can you alt-tab out and do other stuff?
