MenuGui is come visible after death? [Solved]

I tried to put a script to remove this bug but I couldn't do it

Script:

local frame = script.Parent

game:GetService('Players').PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(character)
		character:WaitForChild("Humanoid").Died:Connect(function()
			while wait(5) do
				frame.Visible = false
			end
		end)
	end)
end)
