Use TouchEnded.

local Gui = game.Lighting.HandtoGUI

function GiveGui(Player)
	if Player.PlayerGui:FindFirstChild(Gui.Name)~=nil then return end
	Gui:Clone().Parent=Player.PlayerGui
end
function RemoveGui(Player)
	local gui = Player.PlayerGui:FindFirstChild(Gui.Name)
	if gui then gui:Destroy() end
end

script.Parent.Touched:connect(function(hit)
	local Player=game.Players:GetPlayerFromCharacter(hit.Parent)
	if Player==nil then return end
	GiveGui(Player)
end)
script.Parent.TouchEnded:connect(function(hit)
	local Player=game.Players:GetPlayerFromCharacter(hit.Parent)
	if Player==nil then return end
	RemoveGui(Player)
end
