Expected Result

I'm able to use the playground

Actual Result

Most of the features don't actually seem to work - I can interact with elements like checkboxes and tabs, type in code which gets red squiggles and highlighting, but most of the interaction doesn't actually do anything e.g. switching from "code" to "tsconfig" to "eslintrc" doesn't change the editor content (though it does cause a "Visual Editor" button to appear which does nothing when clicked); likewise for the "errors", "estree", etc.

If I switch to the "ESTree" tab, I do get an "ESQuery filter" input which immediately gives me this warning when I type anything:

Invalid Selector
Cannot read properties of undefined (reading 'parse')

I have tried this on both latest Chrome and Edge, with extensions installed like ublock origins (which isn't reporting anything being blocked, and has been disabled for the site with no luck), with no extensions, and a few other combos, all with the same result.

There doesn't seem to be any errors in the console

Here's another set of screenshots after I've clicked through some stuff and typed again into the editor:

Additional Info

I'd like to have attached a screen recording, but don't have any software for that setup currently - I can look into that next week if needed.

Also let me know if there's any sections of template which you'd like filled out in some way - I skipped most of them as they didn't seem relevant and I couldn't find a more appropriate
