BL2 crashing on startup

Ok. So I had a psycho yesterday and was farming loot midgets. After I was done I saved my game, turned of my Xbox one and went to bed. Today I went to farm some more and my game crashed. I started up BL2 again, same thing. The game works on my brothers account but not mine. How do I fix this? Do I need to delete my psycho? If I do how do I? Thanks for reading.
