Game crashes everytime try to join Crossplay Session

My friends and i are in Act2. I tried to join them in group also they tried to join me…. Everytime we joined each other there game crashes or quit directly.

ME: PS5
They: PC

We played the whole Act1 together and only some issues appears when somebody tries to join a next instance to fast after someone opens it. But now we cant play together anymore…

We attempted to play together again, and we frequently encounter an issue where at least one person cannot enter an area after a zone change or after receiving an invitation. In most cases, it helps if I, as the PS5 player, enter the instance first, but this does not always resolve the problem.

Would providing additional information help?

We found a way to play together without crashes. We noticed that I, as the PS5 player, never experience a crash. In Act 1, I consistently created the group first, followed by one of my friends on PC. If I create the group and send the invitations, the game no longer crashes for anyone during a zone change.

But would be great that everybody could invite to a group without crashes.
