I dont know if this is your case, but if you happened to try the beta (1.1.0) and then reverted back to current branch, then the game will crash whenever you press "Resume Game". What worked for me was to go to my documents->Bannerlord saves and delete -all- saves that got something to do with 1.1.0 beta version, that includes the auto-save. Another user reported that he had to delete the saves in his synch folder too, if you got that enabled.
