Having a game breaking glitch, want to fix it without uninstalling and reinstalling.

So, I have this glitch where I try to load a save, and it starts loading, but then it moves back to the main menu without loading in the save, then if I try to enter any save at all it just breaks the diplomacy menu, I don't know how to make this glitch happen but I'm using the Addon+ mod if it helps.
Honestly its very annoying, it just happens randomly and basically makes the game unplayable with no way to know when it will happen (or at least not that I know of), any help on this or maybe even others that get this same glitch could help
