Well, this is one terrible bug, and one terrible UI change. I don't have Apple Music, I think I was able to set my library as the default view. It's not terribly important (I think ???) to see how large your Apple Music collection is.
I never wanted to install Tahoe, I only took a chance due to these "random kernel panics" that happen every day. My theory on this one is that very few people have my model Macbook pro and so perhaps it doesn't get the intense QA testing and it falls through the cracks. The 2nd to last version of Sequoia fixed my "random kernel panic" but the last version of Sequoia brought it back <sigh> (every kernel panic does send the report to apple though)
