I have a GUI that can play music. I set up a script that should set a bool value to false and prevent more audio from being added, instead I get this error: "Something unexpectedly tried to set the parent of Sound to NULL while trying to set the parent of Sound. Current parent is Workspace." Any ideas?

Script that updates the BoolValue:

game.Workspace.ChildAdded:Connect(function(ch)
	if ch.Name == "Sound" then
		
		game:GetService("ReplicatedStorage").canFire.Value = false
		
		ch.Changed:Connect(function()
			if ch.IsPlaying == false then
				game:GetService("ReplicatedStorage").canFire.Value = true
				ch:Destroy()
			end
		end)
	end
end)

FireServer script that adds the music:

local storage = game:GetService("ReplicatedStorage")
local events = storage:WaitForChild("RemoteEvents")


script.Parent.MouseButton1Click:Connect(function()
	
	local canFire = storage:WaitForChild("canFire")
	
	if canFire.Value == true then
	
	events.PlayMusic:FireServer(script.Parent.Parent.MusicID.Text)
	
	script.Parent.Parent.StopButton.Position = UDim2.new(0.3, 0, 0.94, 0)
	
	else
		
		script.Parent.Text = "An audio is already playing!"
		
		wait(3)
		
		script.Parent.Text = "Play"
		
	end
end)
