I see you got some bluescreens, including this very worrying one:
Windows Error Reporting:
+++ WER0 +++:
Fault bucket CORRUPT_MODULELIST_CLOCK_WATCHDOG_TIMEOUT, type 0
Event Name: BlueScreen
Are these associated with the game crash problem yu mention, or something else?
Either way according to this is is either a driver or hardware fault:
hello I would like to ask what could be caused by a PC with a new new motherboard with a new processor, RAM and GPU ran all well till yesterday and today when I played it fell twice and I threw it ==> Clock watchdog timeout New OS: since September 13, 2019 the problem occurred only today around...

i also see your nVidia driver is outdated so let's do clean reinstall of that and the game:
- uninstall the nVidia driver and all other nVidia software
- reboot
- install the June 2021 driver from here:
Download Drivers | NVIDIA
- reboot again
THEN 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 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.
If you still get this problem after that please attach new copies of all those files, thanks.
