Exhausted script execution time with a time freeze?

Hello, im making a cat stand script, So i was creating a move that freezes "time" but there is a problem, it only works with me and no players, if i use in a server with players it exhausts script execution time and the script ends, even if im using coroutines, nothing is happening. What the script does is make a part and size it while tweening its transparency, also it does a tween animation with the cat, then after the cat animation it goes back and freezes time for everyone while playing a sound, Now the problem is that the wait() exhausts it and the worst is that the sound doesn't remove and it gets removed after ending literally doing the animation lags the entire script, What could i possibly been doing wrong?

-- attack stands for can attack
-- BTW makeSound just makes a new sound and returns it
function StopTime()
	if StandVisible == true then
	attack = true
	character.Torso.Anchored = true
	local el = OriginalCFrame*CFrame.new(-2,4,4)
		local tw = game:GetService("TweenService")
	local info = TweenInfo.new(0.4,Enum.EasingStyle.Sine,Enum.EasingDirection.Out,0,false,0)
	local tween = tw:Create(StandWeld,info,{C0 = el*CFrame.Angles(math.rad(40),0,0)})
	tween:Play()  -- in this part the animation plays
		local part = Instance.new("Part")
	part.Size = Vector3.new(1,1,1)
	part.Shape = "Ball"
	part.Position = character.Torso.Position

	part.Anchored = true
	part.CanCollide = false

	part.Parent = workspace
	local snd = makeSound(138086076)
	coroutine.resume(coroutine.create(function()
		local twe = game:GetService("TweenService")
		local abc = TweenInfo.new(0.2,Enum.EasingStyle.Sine,Enum.EasingDirection.In,0,false,0)
		local twen = twe:Create(part,abc,{Size = part.Size+Vector3.new(50,50,50)})
		twen:Play()
	end))
	coroutine.resume(coroutine.create(function()
		local twe = game:GetService("TweenService")
		local abc = TweenInfo.new(0.2,Enum.EasingStyle.Sine,Enum.EasingDirection.In,0,false,0)
		local twen = twe:Create(part,abc,{Transparency = 1})
		twen:Play()
		twen.Completed:Wait()
		part:Destroy()
	end))
	wait(0.4)
	tween = tw:Create(StandWeld,info,{C0 = el})
	tween:Play()

snd:Destroy()
snd = makeSound(627730102,true)
character.Torso.Anchored = false
	local timeF = true
	coroutine.resume(coroutine.create(function()

		if plr ~= owner then
		coroutine.resume(coroutine.create(function()

	end
	end))
	wait(12)
	timeF = false
	snd:Stop()
	snd:Destroy()
	snd = makeSound(138086076)
attack = false
wait(1)
snd:Destroy()
end
end

Oh my god im stupid, the problem was that i did

repeat
until timeF == false

i should have done

repeat
wait()
until timeF == false

sorry!
