I'm getting the same error and would love if you were able to restore my several-season-old league. I was saving within the game and it hung (I want to say it was at 48%). Not sure why. I have the same error message in the trace:
2021-11-13 10:45:18 load_players: Loading players
2021-11-13 10:45:18 load_players: Error 5
2021-11-13 10:45:18 load_database_files: An error occurred while loading the database! Could not load players file
I zipped up my files here. I really appreciate anything you can do.
