Game crashes while loading a save

Hi folks,
as the thread title says my game crashes while loading a saved game. It happens not only to this special save game it happens to everyone except my new campaign i started to test if i can reload this.

I am playing 2.3 on Windows 10 with a non-steam version of the game. I have a fixed exe to get rid of the copy protection because otherwise i could not start the game. The exe is also possible to use 4GB RAM.

Because this is my first post on this forum i have an external download link for the log:
eb.system.log.rar

Edit: I started another game as Epeiros and the same error occured while the turn for the other factions was calculated. The game crashed when the Lusotannis were calculated. When i killed the faction via console command the game did not crash while calculating the turn.
