Why is this script exhausting execute time

[Miserable_Haven]

this localscript was working before until I added another vehicle and I added debug and it stops after line after detecting if instance is a model it prints and doesn’t work instead lagging me

local Placeholder = script.Parent:WaitForChild("Placeholder")


local function comma_value(amount)
	local formatted = amount
	while true do  
		local formatted, k = string.gsub(formatted, "^(-?%d+)(%d%d%d)", '%1,%2')
		if (k==0) then
			break
		end
	end
	return formatted
end

local function Refresh()
	print("Attempting Refresh")
	
	for _,v in script.Parent:GetChildren() do
		if v:HasTag("Destroy") then
			v:Destroy()
		end
	end
	
	for _,v in game:WaitForChild("ReplicatedStorage"):WaitForChild("Vehicles"):WaitForChild(game.Players.LocalPlayer.Team.Name):GetChildren() do
		if v:IsA("Model") then
			print("What's this "..v.Name.."? OwO")
			local c = script.Parent:WaitForChild("Placeholder"):Clone()
			
			local Price = v:WaitForChild("Price").Value
			
			local new = Instance.new("ObjectValue")
			new.Name = "V"
			new.Value = v
			
			new.Parent = c:WaitForChild("TextButton"):WaitForChild("LocalScript")
			
			c.TextButton.LocalScript.Disabled = false
			
			c.Name = v:WaitForChild("Year").Value.." "..v.Name
			
			--c.LayoutOrder = Price
			
			c.Price.Text = "$"..tostring(comma_value(Price))
			c.MainName.Text = v.Name
			c.Year.Text = v:WaitForChild("Year").Value
			
			c:AddTag("Destroy")
			
			c.Parent = script.Parent
			
			c.Visible = true
			
			print("You've joined the party~! ^^")
			
			task.wait(.1)
			
		end
	end
	
	print("Refreshed :3")
end

Placeholder.Visible = false

script.Parent.Parent:GetPropertyChangedSignal("Visible"):Connect(function()
	Refresh()
end)

it was the price line of the code , I think it’s the co function.
