Provide a description that is worded well enough to be understood

Started getting this for Walker on CW today. Is there anything to be done to get around it or is CW just the latest in the string of streaming sites that are adopting DRM?

Using --check-formats rolls through all the available formats and fails for the same reason.

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

The only thing we can do is detect it earlier and raise before the download stage
