Controlled Pawn cannot move after join a session

The first player creates a session and generates a procedural level (he is doing well with movement).
The second player connects and cannot move. NavMesh is calculated correctly for all players, but I see this in the logs:

LogNavigation: Warning: Was not able to create navigation data for SupportedAgent[0]: Default
LogNavigation: Warning: NavData RegistrationFailed_DataPendingKill.

Moving for the second player works correctly if you set Allow Client Side Navigation = true
But then updating the actor on the server doesn’t work
