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)
