Party not ready bug

Every time I try to join my friends party or invite them to mine it keeps saying unable to join or unable to invite. On top of that when I try to start a game regardless of the type it says party not ready even though it would be only me in the lobby. When I go to the friends screen under my name it says 0 / 0 in lobby as if my character isn't even acknowledged to be in the lobby. I have restarted the game, my playstation, my wifi even deleted and reinstalled the game and nothing works the same bug keeps happening. It makes me consider quiting the game completely.
