How Can We Fix A Tycoon GUI Broken By Roblox Updates?

Since An Roblox Update, The GUIs Used For The Tycoon Are Broken. The "Become Owner" Thing And Buttons Doesn't Disappear (Transparent) Unlike Before. In Studio Mode Everything Works Fine But In Roblox Player It Doesn't. On The Dev Console, It Says That The Error Is On Line 32. There's The Script Bellow And Thanks For Helping :)

local main = script.Parent.Parent.Parent
local owner = main.Owner
local tn = main.Parent.TycoonName
local debounce = false

script.Parent.Touched:connect(function(hit)
    if (debounce == false) then
        debounce = true
        local h = hit.Parent:FindFirstChild("Humanoid")
        if (h ~= nil) then
            local p = game.Players:FindFirstChild(hit.Parent.Name)
            if (p ~= nil) then
                if p.Tycoon.Value == true then
                    for GuiReveal = 1, 0, -0.05 do
                        p.PlayerGui.TycoonGui.Notice.Text = "You already have a "..tn.Value.."!"
                        p.PlayerGui.TycoonGui.Notice:TweenPosition(UDim2.new(0, 0, 0, 50), Out, Quad, 0.5, false)
                        p.PlayerGui.TycoonGui.Notice.Transparency = GuiReveal
                        wait()
                    end
                    wait(3)

                        p.PlayerGui.TycoonGui.Notice.Transparency = GuiReveal
                        wait()
