Hi,
Unsure if you're currently tracking this internally:
Quoting the linked issue:
"""Beginning very soon, you'll need to have Deno (or another supported JavaScript runtime) installed to keep YouTube downloads working as normal.
Why?
Up until now, yt-dlp has been able to use its built-in JavaScript "interpreter" to solve the JavaScript challenges that are required for YouTube downloads. But due to recent changes on YouTube's end, the built-in JS interpreter will soon be insufficient for this purpose. The changes are so drastic that yt-dlp will need to leverage a proper JavaScript runtime in order to solve the JS challenges. """
This will almost certainly affect the VRC builds of yt-dlp.
