Why does this cutscene script work in studio, but doesn't work on normal Roblox?

I'm trying to make an intro sequence with a lot of stuff going on. Here is the script I am using:

-- Locale
local volume = script.Parent
local debounce = false

-- Functions
volume.Touched:connect(function(t)
    if debounce == false then
        debounce = true
        print("Touched!")
        wait(2)
        if t.Parent.Humanoid ~= nil then
            t.Parent.Torso.CFrame = script.Parent.Parent.StandPoint.CFrame
            print(t.Parent)
        end
        t.parent.Torso.Anchored = true
        for i = 0,-2.3,-0.005 do
            game.Workspace.Hotline:TranslateBy(Vector3.new(0,0,i))
            wait()
        end
        game.Soundscape.spookySong:Stop()
        game.Workspace.Hotline.SoundHandle.Moving:Stop()
        wait(0.5)
        t.parent.Torso.Anchored = false
        wait(3.5)
        game.Soundscape.Song2:Play()
        wait(999999999999999999)
        debounce = false
    end
end)

This script works perfectly and as intended in Roblox Studio. But whenever I try to test it outside of studio, it fails to: - Teleport the player - And alter any sort of sounds using the Play() and Stop() events

Why?? Is there something I'm doing wrong? Is it an engine bug?
