Unable to Play Squad Battles.

Playing on Xbox one x. This has happened multiple times.

Random ejection from game.

Game not launching.

As soon as trying to launch a match in-game ( after miraculously making it in) then I am kicked out. 

I can't seem to play ultimate team at all, on ang mode. 

I've got a lot of time invested into the players I have so would be extremely disappointed if it no longer works. 

I've restarted my console, hard reset, clear caches and saved data. I've uninstall an reinstalled. I would prefer options where I don't lose my game data. Please help.....?!??
