[2021] Ps4 split screen error 42.

(Global problem after new update - seems like we need to be patient for a fix on developers side) Hi, ive been playing alot of Rocket League offline lately with my girlfriend trying to teach her the game. When i descided she wad good enough we headed into an online 2v2 or 3v3 casual and it briefly lets us into the game for at millisecond then crashes the match sending us back to main menu with the error code 42 (connectivity issues). I have tried restarting my ps4, reinstalling rocket league, restarting my router, resetting my router and now i am here. We can match offline no problem and one person can match online but not both of us. As soon as we start a casual online game with 2 controllers in the lobby it crashes. I am running a stable 300/300 upload/download with ethernet on my ps4. Would love it if someone had a clue. Btw the epic friend remove thing doesent work either (related to old bug). Ty very much.
