EA FC 24 Career Mode Save keeps crashing in Season 5

I have played 4 seasons of manager career mode without any problems. However, when I go into season 5, I can't save the game and reload it, making the game unplayable for me.

I have tested everything now to make sure my save in season 5 does not get corrupted - but it always does. I can go into season 5, play games, sim games, make transfers, access every single window - there is no problem with anything (I had a managers body graphic disappear in a transfer negotiation, but dont think thats the problem). ONLY when I save the game and then try to reload my save (or continue manager career) my game always crashes without any error message.

I have even simulated through that season, got sacked, had to go to a new club, forcing me into season 6 and well... In season 6 with  a new club, I could save my game again and reload it. But in season 5 it always crashes.

Worth to note: I'm playing a Create-a-Club, but I also don't have any issues with customizing it or anything. Also, there are no players disappearing or something like that. Every single thing works: Except for saving and loading the career mode. I can also reload a save from season 4, continue into season 5, and the same problem will occur again.

Need urgent help or my manager career mode is lost, which would be a punch in the face.
