### Region

China

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

I was able to download videos normally at first, but this afternoon I found that the video download started to report errors. I tested a video on three different IP hosts, and this video was able to download correctly yesterday, but today it fails with an error. I tried different types of URLs and also attempted to add cookies to download the video, but none of them worked. I suspect that Bilibili may have updated its anti-scraping mechanism.And I am very sure that my yt-dlp is the latest version.

### 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

seems like `window.__playinfo__` is removed from the page source now
