Disconnecting from games when playing with a group

Yeah, ever since the new update lets lets you find a team to play with came out, i’ve has issues with disconnecting mid-game. the problem is, it only disconnects when i’m in a group, whether it be from the new group finder or friends i’ve played with for years. i’ve lost about 400 SR and i actually want to play the game i bought with my friends. can anyone help?

Which steps have you tried?
