Provide a description that is worded well enough to be understood

It looks like the fox.com website got a significant redesign over the last couple of weeks, making the default URL style for TV episodes incompatible with the current FOX extractor. Interestingly, the old-style URLs may still be working (for now). Example 1 below shows me successfully redownloading Season 15, Episode 21 of Bob's Burgers ("Mr. Safebody") using the URL I had saved from a couple of weeks ago. Example 2 below shows me unsuccessfully trying to use the new URL format for the same episode. I don't know if the old URLs are just buried a layer deeper, but are still accessible with a minor update to the extractor, or if something more complicated is going on.

Provide verbose output that clearly demonstrates the problem

• Run your yt-dlp command with -vU flag added (yt-dlp -vU <your command line>)
• If using API, add 'verbose': True to YoutubeDL params instead
• Copy the WHOLE output (starting with [debug] Command-line config) and insert it below
