Lineups crashing ultimate team

When I try to open my lineups I keep getting a server error. I’ve deleted the game and redownloaded 4 different times. Unplugged my Xbox and nothing fixes it. The only thing I can think of is I’ve added a season 4 player from the store to my lineup the day the issues started happening. Now I don’t know if I’m doing to have to sell this player for a 1/4th of the 7,700 trophies I bought him for just to get the game to work. Need any ideas before I try that. I was able to get into the lineup screen after promoting someone to starter from my item binder and attempted to autogenerate a lineup but now it won’t even let me back into the lineups again.
