### Region

Denmark

### Provide a description that is worded well enough to be understood

The site www.dr.dk used to work, now I get the error:
**ERROR: Data must be padded to 16 byte boundary in CBC mode**
I've updated to latest nightly build, see also complete verbose output below. 

### 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
