Apple Music on desktop: frequent error, playing stops, asks to refresh

Hey folks,

I've been having this issue recently with Apple Music for desktop. I'll be playing music-- I do a "song of the day" for my seventh grade students, which I play on repeat during the between-bells transition time-- and near the end of the song, the music will frequently stop and I'll get an error that says "An Error Occurred. Something went wrong. Please refresh the page and try again."

It also sometimes happens when I'm just shuffling songs for the students to have some background music while they work.

This hasn't happened to me before when I did this in May, the last time I was playing music for my students. This is the only device that has music open. I'm the only one on my Apple Music account.

Any ideas to get this to stop happening?
