Shortcut "Stalling"?

I have a couple of fairly simple Shortcuts setups, including a “jukebox” shortcut that simply opens a Shortcuts folder populated by individual Shortcuts that “Get Songs from [Playlist]”, “Play [Playlist],” then “Open Music.”

Those shortcuts often “stall” at the “open music” step. They start playing the correct playlist in the background, but the “progress circle” gets stuck and they don’t launch the Music app. Other shortcut widgets that I have can get messed up when this happens until I “force quit” the Shortcuts app.

Any idea what might give Shortcuts a hard time launching the Music app?

Thanks!
