Hi @rosensorcerer, welcome to the community!
Could you ensure that both consoles are on a wired connection?
Have you both tried to reset the console cache or to perform a soft factory reset while keeping games and apps?
Do either of you have any issues connecting to an online server?
We’ll register this occurrence for out team to look into, could you also let us know if your friend is able to join your session?
If possible, could your friend back up the save and experiment with creating a new game for you to try and join?
Apologies for confusing this with a PS4 case, due to platform related limitations it’s not possible to backup saves in a similar fashion on the XBOX.
In any case rosensorcerer please let us know if your friend is able to join your session.
Thank you for keeping us posted, we’ll add this information to the issue ticket.
