Getting kicked out of the game only when playing Ultimate Team (EAFC26)

I have EAFC26 on PC (steam). When I play Rivals in ultimate team, the first 20 minutes of the match always kicks me out of the whole game, the ping suddenly jumps from 30-60 to 1400-2000 and kicks me out of the whole game without any explanation and I don't know how to fix it. I also played a friendly match with friend and didn't kick me out.
