I agree whatever the problem is, is only affecting this game so far as we know. That doesn't mean it has to be the game's fault though! Obviously if this was a game bu everyone would be getting it; there must be something unique in this computer/Windows setup that triggers the problem. Usually I can spot a likely candidate, but no luck so far here.
I see we haven't done a full **clean** re-install:
- move any valued save games elsewhere
- "uninstall" in Steam-Imperator
- manually delete both the Steam/SteamApps/common/Imperator AND Documents/Paradox/Imperator folders
- re-install game in Steam, run a Steam Verify when done.
- add imperator.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 you need to make sure there are no files or folders left under either the Steam Imperator or Documents Imperator locations, before installing again.
If that still doesn't help, please attach here all files in the /logs/ folder that are over 0 bytes, thanks.
I wish I could say that it is working now, but sadly still same result
