So, i m doing a loading screen but my script doesn t show any errors, is a localscript and when it finishes i want it to make my MainGUi Enabled after the loading screen goes, but it doesn`t.

game.StarterGui:SetCore('TopbarEnabled', false)


script.Parent.MouseButton1Click:Connect(function()
    if script.Parent.Parent.Visible == true then
        script.Parent.Parent.ImageButton.Visible = false
        script.Parent.Parent.MainMenuButton.Visible = false
        script.Parent.Parent.ImageLabel.Visible = false
        script.Parent.Parent.GameTitle1.Visible = false
        script.Parent.Parent.GameTitle2.Visible = false
        script.Parent.Parent.SongTitle.Visible = false
        script.Parent.Parent.MadeBy.Visible = false
        script.Parent.Parent.ComDiscordServer.Visible = false
        script.Parent.Parent.DiscordLink.Visible = false
        game.ReplicatedStorage.Teleport:FireServer()
        game.StarterGui:SetCore('TopbarEnabled', true)
        game:GetService('StarterGui').MainGUi.Enabled = true
        while true do
            wait(0.07)
            script.Parent.Parent.BackgroundTransparency = script.Parent.Parent.BackgroundTransparency + 0.01
            if script.Parent.Parent.BackgroundTransparency == 1 then

                break
            end
        end
        if game.SoundService.Folder["Walker Alan - Darkside Remix"].Playing == true then
            wait(10)
            game.SoundService.Folder["Walker Alan - Darkside Remix"].Playing = false
            game.Lighting.Blur.Enabled = true
            game.Lightning.Blur.Size.Value = 1.5
        end
    end
end)
