Description

I was using youtube-dl and attempted this video and was presented with a new issue -- The video: https://youtube.com/watch?v=Dk2QFXMHM88

I can play the video and I tried downloading it from the command line as well as in my code and the message is the same. I do not see this issue elsewhere in the issues forum.

Thank you - JM

Although the actual crash is different, your diagnostic and line numbers match #32314. Presumably new YT player JS is crashing that version of jsinterp.py in a different way.

Please update your yt-dl code again from the master or from the nightly .tar.gz, or install a nightly build. See #30839.

Using this sudo -H pip install --upgrade youtube-dl. - I get:
Requirement already satisfied: youtube-dl in /var/miniconda3/envs/transcriber/lib/python3.10/site-packages (2021.12.17). --

However, doing this pip3 install --upgrade "https://github.com/ytdl-org/youtube-dl/archive/refs/heads/master.zip".
this fixed the issue.

I am no longer able find a link to the instructions that I saved above on the github site or downloads page. Maybe put it in the installation or update section.

Thank you for youtube-dl and the super fast help,

Jack

--force-reinstall may have helped in the first case.
