Some song won't play in Apple Music on Mac- fine on iPad or phone

Seems random songs I have purchased from Apple/iTunes Store over the years now won't play. no pattern I can see. Most do play fine. but every so often a song or whole album if you hit play the icon to changes to the "playing" then switches right back to the "play" button. very annoying as I have purchased and paid for these songs...

Only happens on Mac Studio, works fine on my iPad and iPhone.

Ideas?

thanks
