media_change event not firing

Not 100% sure it's OS upgrade related since I'm changing my config quite a lot in the past few days and I can't remember when my nowplaying widget stopped to show, but I think it is caused by my upgrading to latest macOS Sequoia 15.4.

Now media_change no longer triggers (I test this by echo-ing date and $INFO into a log file in the script and play/pause a few times, but I would only see one line outputted by the initialization). Tried rebooting and with Spotify, Music, browsers etc. and none worked.
