Microsoft Learn Lab Stuck Loading

The labs for Microsoft Learn seem to have suddenly been stuck on a loading loop, unable to display the launch button. I have viewed the runtime compilation and believe these two errors to be the cause:

Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('https://client-api.arkoselabs.com') does not match the recipient window's origin ('https://learn.microsoft.com').

value @ api.js:15
value @ api.js:15

Uncaught (in promise)

  1. Object
    1. Error: "API consumer not enabled"
    2. Status: 0
    3. [[Prototype]]: Object
      1. constructor: ƒ Object()
      2. hasOwnProperty: ƒ hasOwnProperty()
      3. isPrototypeOf: ƒ isPrototypeOf()
      4. propertyIsEnumerable: ƒ propertyIsEnumerable()

      10. lookupGetter: ƒ lookupGetter()
      11. lookupSetter: ƒ lookupSetter()

See if you can figure why it has stopped loading; I have troubleshooted the issue earlier (trackers and cookies allowed, adblockers and vpns off, incognito mode, cleared browser, etc), so it might be a server side issue.

Thanks in advance!
