Getting error "Could not parse decipher function" whenever I play anything.

[gabriel-eladi]

What's happening?
I've been using Muse for a few months now, it was working perfectly. Starting today, I began getting an error 🚫 ope: Could not parse decipher function: Error: Could not match ;([A-Za-z0-9_$]{2,}).\w+( whenever I try to play a song (through a Spotify link, a YouTube link, a YouTube search, none work).

Logs
(I only censored my guild ID)

Additional context
I have tried downgrading to 2.7.1, but I get the same error. To my inexperienced self, it looks like the issue lies with ytdl.

• Inside a Docker container

Randomly started today. Maybe this has something to do with YouTube changes.

[0xC4DE]

Issue with me too. Just started with Youtube specifically. Not with spotify.

[STK0Cervanthes]

yeap same here too

Fresh set up done a few hours ago

joins the VC thinks a lot and then gives that error for both Spotify and Youtube

[torkd]

Had the same problem yesterday. Building the docker image from this PR which migrates to play-dl mitigates the issue (as in it will reproduce songs from youtube, it will still think a lot).

[gabriel-eladi]

suddenly, without changing anything, the bot seems to work for me now. it does think longer than usual though.

[gabriel-eladi]

since the issue seems to have fixed itself, i will close it now.
