I have a Google Apps Script project that I have used for the past few months (successfully) and everything has worked just fine. A few weeks ago, I started getting the "Unable to load files" error whenever I attempted to test the project or send updates. I think I've tried everything; I've cleared caches, used different accounts, used different files, used Safe Mode, different browsers, disabled/deleted extensions. I even got in contact with out G-Suite support for our organization and they couldn't help.
Oddly enough though, the only computers upon which I am unable to operate Google Apps Script are my work computer and home computer. I've run tests completely fine on co-worker's machines and even a machine at my school.
I don't know how to check if my account/computers have been blacklisted, and I've tried spoofing my MAC address and it still didn't work. Any ideas?
* UPDATE *
It has been quite a while since I've posted two different issue requests on the Issue Tracker, without any response from any Google employee. Since the initial post, I've tried completely wiping my computer (literally destroying all data on it) and that still didn't do the trick. I did that after I logged on with a coworker's computer and it worked, but still my own machine throws the same error.
Best Answer
I haven't found anything official about Google Apps Script MAC address blacklist on https://developers.google.com/apps-script. There is a tool for monitoring scripts at https://script.google.com, but it doesn't including anything related to developer devices.
I suggest you to search for a related issue on the official issue tracker and if you haven't found anything, post a new one.
