Cloud Music Library stuck updating
When I try to add music to my Cloud Music Library from my Mac (macOS 12.2.1), I get "Updating Cloud Music Library" with a continuously spinning wheel at the bottom of my Apple Music window, and the activity window just shows one row that says "Loading Cloud Music Library..." and a second that says "Cloud Music Library: Updating Cloud Music Library", with a spinning black wheel next to the second row. This persists for hours/days with no resolution. I have at least one album on my computer that is not in the Apple Music library (Brenn Hill, Trail Through Yesterday), so I don't know if that is what's causing the issues, otherwise, I don't have any ideas on how to go about fixing this.
Thanks in advance for any help!
