how can i stop a script that edits a character from repeating every time a new player joins?

i added a script i found on google to my game to replace character model names however it repeats every time a new player joins which would constantly respawn a player, how can i fix this?

game.Players.PlayerAdded:Connect(function(player)
    local ignore = false
    player.CharacterAdded:connect(function(oldCharacter)
        wait(1)
        if ignore then return end
        ignore = true
        spawn(function()
            player.Character = nil
            oldCharacter.Archivable = true
            local newCharacter = oldCharacter:Clone()
            newCharacter.Name = player.PlayerNameValue.Value
            player.Character = newCharacter 
            newCharacter.Parent = workspace
            if newCharacter:FindFirstChildOfClass("ForceField") then
                while oldCharacter:FindFirstChildOfClass("ForceField") do
                    oldCharacter.ChildRemoved:wait()
                end
                repeat
                    local forcefield = newCharacter:FindFirstChildOfClass("ForceField")
                    if forcefield then forcefield:Destroy() end
                until not forcefield
            end
            ignore = false 
        end)
    end)
end)
