_No response_

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

I am encountering an issue with downloading multiple videos from iQIYI. About a week ago, everything was working fine. However, now I am consistently getting the following error:

Unable to download webpage: HTTP Error 413: Request Entity Too Large

To temporarily resolve the issue, I have to repeatedly refresh the iQIYI page and export a new cookie. This workaround is inconvenient and disruptive.

### 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
