MUT lineup problem

Everytime I try to open my MUT lineup I immediately get kicked from the mode getting sent back to the selection screen, I have just bought 2 new players and cannot properly activate them I have tried the ea help ai I have done everything it told me to and nothing  has worked, I have restarted and re installed the game and nothing has changed. I checked the Xbox servers to see if anything was down and it was perfectly okay, for the past 2 days I haven’t been able to see my lineup and the game says that they “cannot process my request”  and kicks me. Someone from ea help. I’ve even tried to access the lineup from different spots like practice and it hasn’t worked. Any way of opening my lineup right now is unavailable
