Music won't play songs from a shared library

I have enabled my 15 inch M2 MacBook Air to share Music libraries between user accounts on the same computer. I am using Mac OS 14.7. The shared libraries appear complete in the Music app of the other accounts, but the music won't play. Nothing happens when I select a song to play, and its title does not appear in the title window at the top where the progress bar appears. Rebooting the MBA did not fix the problem.
