I've never seen anything like this:
Did your clean reinstall look like this?
[17:23:44][pdx_data_factory.cpp:912]: Could not find data system function 'Linie'and frankly have no idea what could cause that.
[17:23:44][pdx_data_factory.cpp:697]: Failed converting statement for 'Linie'
Did your clean reinstall look like this?
- move any valued save games elsewhereRead more
- "uninstall" in Steam-CK3
- manually delete both the Steam/SteamApps/common/CK3 AND Documents/Paradox/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
