District system is working, but, it keeps appearing on the screen. Help?

So, I want to make like a District System with Region3 and when you are going into a specific area, a GUI should pop up. It works, but, it keeps appearing after 5 seconds on the screen, which I don't want to. It's a local script. Anyone knows how to fix it? I've tried to do it with debounce too, but it didn't work.

local DistrictsWorkspace = game.Workspace:WaitForChild("Districts")

local Found = false


debounce = false

while wait(1) do
	
	for i, v in pairs(DistrictsWorkspace:GetChildren()) do
		
		Found = false
		local region = Region3.new(v.Position - (v.Size/2), v.Position + (v.Size/2))
		
		local parts = game.Workspace:FindPartsInRegion3WithWhiteList(region, game.Players.LocalPlayer.Character:GetDescendants())
		
		for _, part in pairs(parts) do
		   if part:FindFirstAncestor(game.Players.LocalPlayer.Name) then
			print("Player was found!")
			Found = true
	        break
		else
			Found = false
			print("Player wasn't found!")
			end
		end
		if Found == true then
			if game.Players.LocalPlayer.PlayerGui.Districts[v.Name].Enabled == true then
				game.Players.LocalPlayer.PlayerGui.Districts[v.Name].MainFrame.Visible = true
		        wait(5)
                game.Players.LocalPlayer.PlayerGui.Districts[v.Name].MainFrame.Visible = false
				break
				end
else
			    game.Players.LocalPlayer.PlayerGui.Districts[v.Name].MainFrame.Visible = false
		end
	end
end
