Split Fiction Error Code 108-0

Me and my friend have played around 4 hours so far across two sessions. Originally we experienced this error code, on our second session we did not, and now on our third session we are again experiencing the error. He plays on Xbox Series S and I play Playstation 5. As I'm writing this, he now cannot see I'm online at all. (Update: it fluctuates between either he invites me and we get error 108-0 or he can't see I'm online) He owns the full game and I own the friend's pass. Hoping this get's fixed soon :)
