[2020] Unhandled Exception C0000005 (EXCEPTION_ACCESS_VIOLATION), craches

Ailis7 said: The problem is reproduced when loading the game, no matter where, even during the game, if loaded from the place where you are currently playing - crash to the desktop.

Can you clarify this please? Do you mean this only happens when you load a saved game while you are in a game? Not from the main menu?  

Ailis7 said: In both cases. I meant that the game is not interrupted, and you can play as long as you want. But you can't load in any way.
Look at the video in my comments. There I demonstrate in detail the reproduction of the problem, thanks!

Are you using cloud saves? If so they are probably corrupted. Can you test with a new campaign with local saves only please?  

I was able to load and run that game for a couple of years at least, no problem. Is there some action or choice in that game that triggers a crash for you?
