I’ve experienced this same thing - it’s driving me nuts!
It’s interesting that this doesn’t appear to have been from an update, this same version worked and then stopped working and it’s been at least a week now. I also can’t get StreamFab to grab it from YouTube Music - so for me it’s consistent there, too. I don’t know enough about the technical implementation and typical points of failure, but my guess is it’s from the YouTube side of things.
