I do Have this issue too it just happened today even though i have had this for half a year already and never had this issue
has anybody figured out anything because deleting the app data doesn't work right now
Another note if you enable blocklist in ad blocker it will work

Another note i wanted to mention i decided to keep rolling back version to see if it was something new but i went all the way back to 2.0.1 and still had that same error
something to note while on the version 3.0.0 it didn't give me the syntax error instead a # name error thing
just something to note
Funny enough
Another note i went to down to 1.0.0 it just gave multiple errors and didn't even launch for me

After inspecting the source code and playing with it for a while, I've found that:

This issue seems to be related to a dependency of the YT-MUSIC app (Youtubei.js)
Issue#683 in LaunRT/YouTube.js

Downgrading the package doesn't seem to work. (Looks like a change in the youtube API broke the package)

[JellyBrick]

This issue was caused by a breaking change in the YouTube internal API.

See LuanRT/YouTube.js#683

The new package version of Youtubei.js fixed this issue; I've tested it on my own machine and it passed all tests like normal.
