I have the same problem.
Attempting to load a game save first gives an error message which says it cannot load the game, second attempt crashes the game.
This started happening to me after banking maybe 10 hours of gameplay in total.
I’ve seen other posts on about this dating back to November 19: Load saved game failled
I can’t find a response from Microsoft or any fix. It also doesn’t appear as a known bug as of yet.
I’ll reinstall the game and update.
*reinstall didn’t help.
