When I try to connect the 4th player in the games, I always get the message: You’re restricted from using communication features. 

I’ve authorized everything in PlayStation accounts and in Microsoft/Xbox account. (In ps account if I unauthorized the communication, when I get the error message, I can ask for the manager to authorize the games. I try it and I see minecraft in the authorization and it still not work). And I get the message with every kind of account I creating.

I try to do the unshared and share of my PlayStation 5 pro.

I try to redo the license for the Minecraft ps5 version.

I try with a new seed.

I try with a game on the realms server.

I finally have the idea to try with the PS4 version and surprise I was able to play 4 players in split screen but in a local world. If I try it in my realms world when I pop the 4th player, the games crashed completely.

So I speak with PlayStation, they have no solution (they think to replace my ps5pro) but I know its not the issue.

I speak with Minecraft teams and they have no clue and redirect me here.

So I hope someone can have a clue because I’m out of it ...
