Live Events/Rivals Co-Op disconnections.

Everytime i'm trying to play co-op with my friend (i'm on PC he is on PS5) we get disconnection at the beginning of the match and it's usually few seconds after match starts, also we tried to switch the teams, close the game, reset our internet connection (we both use ethernet if that is important), it's so frustrating and makes us to lose interest to play the game and considering we both bought ultimate version of the game it's too much to be happening almost every match. 

ps. my connection score is good.
