### Region

Switzerland

### Provide a description that is worded well enough to be understood

I'm using yt-dlp on a script of mine and I realised that one of my tests was flakey. In particular, listing playlists for a given YouTube channel would fail about 33% of the time, but nothing in my code seemed amiss.

Searching through the issues to see if I was doing something wrong or there was someone having similar trouble, I found https://github.com/yt-dlp/yt-dlp/issues/11511 (not related to my issue per-se), so I tried the exact command that was suggested to see if I could replicate my issues there, and indeed, I'm having the same trouble using the CLI command.

More than half the times, running the command `yt-dlp -vU --print "%(id)s|%(title)s|%(playlist_index)s" --flat-playlist "https://www.youtube.com/@LibraryoftheUntold/playlists"` works fine. But occasionally, it silently fails with no output or warning. It just doesn't print anything. When using the Python library directly, the issue manifests as an empty list in the `entries` key, whilst all other fields seem to be populated as usual.

### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [X] If using API, add `'verbose': True` to `YoutubeDL` params instead
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
