Ok, so the issue is most likely that Noble isn't picking up your Bluetooth adaptor.
'Noble' has this video linked showing you what you need to do to set it up: https://www.youtube.com/watch?v=mL9B8wuEdms&t=106s
It's often a lot more sensible to add an external Bluetooth dongle which Noble can then pick up and use (rather than trying to use Zadig on your internal adaptor, which then stops normal Windows from using it)
Unfortunately Bluetooth LE with Node.js on Windows is a mess right now. It's one of the reasons I push everyone to the Web IDE - because it 'just works'.
