How To Make A Teleporter Gui That Show When A Player Touch A Part?

Hi, I have a question, I've made a Teleport Gui for Players on Mermaid High and It's worked in a part that i made on December 2020 but when i change the Gui for another it's doesn't work.

local Part = script.Parent
local Debounce = false

Part.Touched:Connect(function(hit)
	if Debounce == false then
		Debounce = true
		if hit.Parent:FindFirstChild("Humanoid") then
			local plr = game.Players:GetPlayerFromCharacter(hit.Parent).PlayerGui
			script.ScreenGui:Clone().Parent = plr -- replace "ScreenGui" with the name of your ScreenGui
		end
		wait(1)
		Debounce = false
	end
end)

Also i changed the Name on ScreenGui in the script and stop working

When it's opened: https://gyazo.com/e3da7e8b5c4ed37bc965e4681ecb9548

When it's not opened: https://gyazo.com/49fc25b4c7b71fe68f30143bf85ea0d3

Can anyone can help me?

FIXED CODE

local Part = script.Parent
local Debounce = false

Part.Touched:Connect(function(hit)
    if Debounce == false then
        Debounce = true
        if hit.Parent:FindFirstChildWhichIsA("Humanoid") then
            local PlayerGui = game.Players:GetPlayerFromCharacter(hit.Parent).PlayerGui
            PlayerGui.ScreenGui.Enabled = true
        end
        game.RunService.Heartbeat:Wait()
        Debounce = false
    end
end)

EXPLANATION

on line 9 make sure to change ScreenGui to the name of yours.

swapped the

wait(1)

with

game.RunService.Heartbeat:Wait()

I think run service might be good in this situation. You should never use wait(n) or wait() because it can be really bad for performance instead wait for events like what I did. There'll always be an event for different situations.
