Script resetting a gui and a localscript not working the second time?

So I want a certain Gui, with a script in it, to reset to it's original state. (So the script resets, and all the texts and frames are back in the original position) To do this I came up with the following script. It works once, but then it gives the following error.

ERROR: The Parent property of BackGround is locked, current parent: NULL, new parent EndGui

I know that the error is caused because I try to clone the thing that I just destroyed, but my intention is to clone the Gui as it was in the beginning of the game, when nothing changed yet. Is there any way I can do this?

script:

local BackGround = script.Parent:WaitForChild("BackGround")
local CloneBackGround = BackGround:Clone()

local NetCodeValues = game.Workspace:WaitForChild("NetCodeValues")
local Ending = NetCodeValues:WaitForChild("Ending")


Ending.Changed:connect(function(Value)
    if Value then
        script.Parent.BackGround.EndLocalScript.DestroyValue.Changed:connect(function(Value)
            if Value then
                script.Parent.BackGround:Destroy()
                CloneBackGround.Parent = script.Parent
            elseif not Value then
                BackGround = script.Parent:WaitForChild("BackGround")
                CloneBackGround = BackGround:Clone()
            end
        end)
    end
end)
