My steps to solve my crash problem:
1. I go into Documents and find the "Mount and Blade II Bannerlord" folder, make a copy of all the files in this folder and create a new folder (MB2) and drop all the files there.
2. Delete the "Mount and Blade II Bannerlord" folder and launch Bannerlord through Steam (any version)
4. To return the old saves, you need to go to Documents and find the new folder "Mount and Blade II Bannerlord", go into it and find the Game Saves ---> Native folders, leave it and go to the folder (MB2) where you saved the files from the remote folder and find in it the same Game Saves ---> Native folders and copy all the files and transfer to a new folder.
5.Go to the game and load any save and play)
P.S. if it doesn’t work, uninstall Microsoft OneDrive and try again.
