How to fix this team gui player:LoadCharacter() script?

Does anyone know how to fix this problem?

I have made a team changer GUI and I don't want to "kill" the player instead I just want to load the player in with player:LoadCharacter() if I can. The script will work in studio but it won't in game.

Here is my code.

local player = game.Players.LocalPlayer

script.Parent.MouseButton1Click:connect(function()
player.TeamColor = BrickColor.new('Really red')
    player:LoadCharacter()
end)

I am using a local script.
