Game keeps crashing after saving

Hi !

Everything in my game is smooth except the fact that when I try to save (the 3rd ou 4th time after launching the game), it crashes. I got rid of my mods and repaired the game, nothing works out. When saving, the icon ''saving'' appears and the animation stops, just to crash afterwards.

I also have a nice pc, and enough space, so I don't get why it crashes.

Thank you for your future help ! 😊
