Provide a description that is worded well enough to be understood

yt-dlp --dump-json is broken in 2023.06.21. I tried it with 2023.03.04 and it works fine. I tried it with a few Twitch videos at first because i thought it was the video but it seems like it is just broken. All of the videos work fine on the 2023.03.04 though.

Here are some links to test :

https://www.twitch.tv/videos/1851391690

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

fixed in master, install from master branch with pip
or use --netrc-cmd "" or --netrc-cmd= as workaround.
(or wait for next proper release, coming soon)
