FYI, I had this same issue and finally figured out how to solve it. The problem is a conflict between the game and OneDrive backing up the Documents folder.
To fix I removed Documents as one of the backed up folders for OneDrive. Went to OneDrive Settings -> Sync and Backup -> Manage Backup, from there deselect the Documents folder. It'll ask you if you want to confirm, so say "Stop backup and choose where to keep files", then select "Only on my PC". It might orphan some files on the OneDrive cloud storage, but you can manually download those or delete them as needed.
