BTT repeatedly quitting (and restarting) when Apple 'Music' app plays/pauses

Note:
Before bug reporting, please make sure you have tried the latest (alpha) version of BetterTouchTool and that you have already tried to restart your system :-). If you encounter a crash, please attach a crash log from the macOS Console.app's "Crash Reports" section.


Describe the bug
When a song starts or is paused in the Apple Music app, BTT will immediately quit, then re-open a few seconds later.

This is triggered when a song starts playing (whether by unpausing, skipping to next song, or when a song ends and the next song on playlist comes on naturally) and upon pausing a playing song. Other operations in Music (eg changing volume) don’t trigger it. Playing the same tracks using another app (Swinsian) doesn’t cause the problem, it’s only the Apple Music app (1.5.6.11).

This started a couple of days ago when I updated to the new main version of BTT, but downgrading to an older version didn’t fix it.


Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):

Device information:

  • Type of Mac: Mini M4
  • macOS version: Sequoia 15.7.5. I tried upgrading to Tahoe 26.4, but it didn’t change anything. I downgraded OS back to Sequoia for other reasons.
  • BetterTouchTool version: Currently 6.320, though I tried reinstalling 6.219 from about a month before the problem started, and it also occurs.

Additional information (e.g. crash logs, related issues, etc.):

weird issue! Could you post the crashlog from macOS console app's crash report section?

Here’s a fresh one

It seems to be due to some unexpected return value when using a now playing widget (TouchBar, StreamDeck, Floating Menu or NotchBar). It should not crash anymore with 6.322!

What a legend, thanks so much, yes that’s fixed it! I forgot to mention I have a “now playing” widget which displays in the menubar.
