Hello and sorry about the issue! A user yesterday mentioned it to us in Support. I was able to reproduce, yesterday and today. Sort of.
A refresh worked for me Just a refresh, not a hard refresh, so close your console when doing it. Let us know if that works, and note you can skip ahead using the Toggle Navigation button at the top of the challenge.
Got those same errors, too, which are in some code that checks Docker solutions. I've recorded those already, and thanks for posting a screenshot! I'll add your report to the issue and escalate this if others start noticing this as well.
