i get that unexpected run time error as well
Ok, I misunderstood one of your post and thought you said that it did fault with the output removed.
But the LED not working unless the laptop is plugged in still leads me to a ground problem
Or, is it possible that your 24 VDC is getting tied to your 120 VAC somewhere in your output wiring? You did say you switches had 120 VAC indicators. You are not using Neutral and 24 VDC common for the same thing are you?
