### Region

The Netherlands

### Provide a description that is worded well enough to be understood

The most recent fix I could find was from pull #1877, but that is not working any more.

However @dirkf adapted his pull request [ #29318](https://github.com/ytdl-org/youtube-dl/pull/29318) in the youtube-dl repo yesterday and that does work.
Tested with:
https://www.redtube.com/40022171

### Provide verbose output that clearly demonstrates the problem

- [X] 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
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
