Host and clients can't move on server

Hello, and thank you for taking your time to help me.

I have a problem with the movement of my players.
Indeed, when a player creates a session neither he nor the clients can move.
What is strange is that when I launch the world in which the players can’t move in listen server, they can move.
This problem occurs only when I go through the creation of a session.
I am attaching my session creation code:



Thanks in advance for your help.
