Some Players are Spawning as Michael and Invinsible

Somehow some players starting to spawn as michael and invisible, tried a workaround. Someone having same problem?
Citizen.CreateThread(function()
while true do
Citizen.Wait(500)
SetEntityVisible(PlayerPedId(), true, 0)
end
end

Same here. Since few days now, some of our players are spawning and are invisible for everyone else. If we spectate them, we see them as micheal at the character creator in the airport. But the problem doesnt affect all the clients just some of them and not always the same clients either
