Udemy: "Unable to extract csrf token"

[maxigaz]

Playing videos on Udemy using mpv + youtube-dl has stopped working recently. I get the following error message in the terminal:

[ytdl_hook] ERROR: Unable to extract csrf token; please report this issue on https://yt-dl.org/bug . Make sure you are using the latest version; see  https://yt-dl.org/update  on how to update. Be sure to call youtube-dl with the --verbose flag and include its complete output.

And here is the output of youtube-dl -v:
