make that 4!
Can't load anything, game instant crash.
I tried out the beta, and then had to revert later so I could play with friends on Multiplayer. I experienced the same problem as you have. It seems if you got a save file that is 1.1.0, the game crashes when you try and press the "Resume campaign" button.
I fixed this by going into documents->Bannerlord saves and deleting any save that had something to do with the beta, 1.1.0. That includes the auto-save.
