### Please make sure the question is worded well enough to be understood

Earlier I could download videos from hotstar if I use login cookie but recently after yt-dlp update now I can't download video even using login cookie. I was also able to download yesterday on the same system.

### 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
