I can’t play Split Fiction with my friend on PS5 Error Code: 108-0 or 108-3

Hey guys, 

I can’t play Split Fiction with my friend together. We both play on Ps5 and both of us have the game. We try to play the game since release and till this day were not able to do so. We can load into the game and see the first scenes where the two arrive and also when Mio comes into the other's world. From there we come to the purple loading screen and one of us is then kicked. We don't know which of us because it says both for me and my friend that the other player has left the session. We get the same Error code over and over again and it’s really frustrating. The error code is: 108-3 or 108-0. We‘ve tried so many things like restart the game, restart the ps5, link and unlink our EA Accounts, delete the Game or play with the friends pass. We don’t know what to do from here so I hope you guys can help me fix this.
