Why does iTunes crash at startup on macOS Sequoia 15.4.1?

macOS intel - sequoia 15.4.1

iTunes V?? - don't know 'cuz it won't start

iTunes crashes at startup. I have sent about 5 crash reports to Apple. It as working until recently, the last 3 months.

The Music app on imac does not recognize iTunes' data, so cannot play any music from playlists. :-(.

Any remedial suggestions?
