PS5 Squad Matchmaking Blocked When I’m in the Group

Hello everyone, is anyone else having this problem? For two days now, I can only join games by joining other players. My squad – all PS5 players, me as well – can’t search for a match when I’m in the group. That means I always have to join afterward. That was already annoying, but now the game is also super laggy for me. Does anyone have an idea how to fix this?
