Technically bug in Madden 26 ultimate team mut duos

So basically I’ve played with my friend everyday until 2 days again this error started. Everytime we ready up this error pops up when it says our opponent has joined the lobby and it won’t let us played we tried about 20 times and it still doesn’t work. In madden 26 ultimate team mut please help me solve this problem. I’ve spent so much money, and on top of everything so many hours on this game!
