I cannot download anything via yt-dlp for a couple days too. Probably Google's shenanigans. yt-dlp got an update regarding this and it might not have hit your distro's repo yet. Shouldn't take long.

Make sure it is updated to latest nightly (they constantly play whackamole with YouTube's changes breaking downloader and monthly stable basically never works)

If you're using your distros install, uninstall it, create a Python venv, and install yt-dlp using pip. Distro packages do not update frequently enough to keep yt-dlp usable, the pip version is latest nightly build by default.

Make sure you have a JavaScript anti-bot challenge solver installed, which is the yt-dlp-ejs package, and a JS runtime like deno else YouTube will always fall over

You didn't give us much information to go on, but you should probably start by getting the most up to date version of yt-dlp. Also, I believe some time ago that it became a requirement to run another service in other to get youtube content.. EJS it's called.

Paste the FULL output

When accessing yt make sure you always update to nightly, stable take too long to get the updates.

--update-to nightly

Maybe someone here can help if you provide the error message

working for me with updated binaries (currently on windows), including deno.

using just the cli instead of ytinterface. fed it a random playlist i found and used your exact command line. it also stated music wasn't supported but redirected seamlessly to yt itself.

it's now 40-some tracks in and still going.
