How to check if part has touched another and delete with while true do loop?

I'm trying to check if a part has touched another part and if it has, delete the part(itself) after that but roblox studio keeps crashing every time I try to do that.

local ball = script.Parent

while true do
	wait(.5)
	repeat
		local newball = Instance.new("Part")
		newball.Parent = game:GetService("Workspace")
		newball.Size = Vector3.new(41.599, 9.74, 52.861)
		newball.CFrame = CFrame.new(-71.199, 203.093, 59.05)
		newball.Anchored = false
		newball.Color = Color3.fromRGB(165, 0, 2)
		newball.CanCollide = true
		
		newball.Touched:Connect(function()
			if newball:FindFirstChild("Baseplate") == true then 
				newball:Destroy()
			end
		end)
		
	until ball.Position == Vector3.new(0, -8, 0)
end
