I can't hear any music :(

[IsaacD3vs]

Hello, let me introduce myself, I'm Isaac. I would like help with the app, I have been using it as usual for almost 7 months now. However, today as usual, I wanted to add new music to my catalog and playlist, but it simply couldn't be heard, much less loaded, just an "unknown error" and that's it. So with all the music I was looking for, removing the ones I already have. I tried to exit and log out of yt music but nothing, I tried to uninstall the apo and nothing. Please help, this app is one of the only ones that charge me for listening to simple music. Very kindly, I wish you a nice night.
