Why isn't TweenService working in-game, only studio?

I am making a music visualizer, and this script works perfect in studio, but when I go into an actual game it doesn't work.

there are no errors either.

Code:

wait(1)
local ts = game:GetService("TweenService")
local music = workspace:WaitForChild("Music")
local lookAt = workspace:WaitForChild("lookAt")

while wait() do
	local bass = math.ceil(music.PlaybackLoudness/6)
	local props = {
		Color = Color3.fromRGB(math.random(bass, 255),math.random(bass, 255),math.random(bass, 255));
		Size = Vector3.new(bass,bass,bass);
		Orientation = Vector3.new(0,0,-175)
	}
	
	if (bass < 25) then
		props.Orientation = Vector3.new(0,0,140)
	elseif (bass > 25) then
		props.Orientation = Vector3.new(0,0,-175)
	end
	
	local tweenInfo = TweenInfo.new(0.25, Enum.EasingStyle.Quad, Enum.EasingDirection.Out, 1, false)
	local tween = ts:Create(lookAt, tweenInfo, props)
	
	tween:Play()
	
	lookAt.ParticleEmitter.Color = ColorSequence.new(Color3.fromRGB(math.random(bass, 255),math.random(bass, 255),math.random(bass, 255)), Color3.fromRGB(math.random(bass, 255),math.random(bass, 255),math.random(bass, 255)))
	lookAt.ParticleEmitter.Rate = bass
end
