Tahoe music library does not open.

Just now upgraded to Tahoe OS on my new 2025 Mac book Air and what the heck: Apple Music library does not open. At all. Disaster for me.

I leave it in swirling circle progress mode for hours and no success. My playlists names are still there on the left but there is not the library of songs (I have several thousands of songs)

I have been loading about five CDs per day from external CD DVD drive and have been doing that for many years, up to Sequoia, no problems. Now suddenly Tahoe library will not open. Does anyone have advice, solution to solve? Thanks!!
