Creating the most optimized Roblox game- runs at 6000+ FPS!

I found out that disabling this script fixes the bug.

game:GetService("Players").PlayerAdded:Connect(function(player)
	local PlayerGui = player:WaitForChild("PlayerGui")
	for _, GUI in ipairs(game:GetService("StarterGui"):GetChildren()) do
		GUI:Clone().Parent = PlayerGui
	end
end)

I made this to transfer every ScreenGui from StarterGui to PlayerGui as they won’t be inserted automatically because Players.CharacterAutoLoads == false.
