I have a MX Keys keyboard, connected via bluetooth, and recently, the media keys just don't work anymore.

If I use something like BeardedSpice, it does, but I don't get why it doesn't work without it as well...

Volume keys work fine though, just the play, next and previous aren't working (on any player).

I don't know what could possibly cause this. Any ideas?

EDIT: best guess is some app is "stealing" the key presses, not sure how to find out if that's true and if so, which app.

EDIT 2: tested in another user and it works. Also did reset SMC et al. My best guess still is that something is stealing the keypresses, no idea what nor how to find out.

EDIT 3: the macbook's physical keyboard also do not work.

EDIT 4: it seem to have stopped working when I briefly migrated from apple music to spotify. Media keys didn't work on spotify, so I assumed it was a spotify issue, and started using bearded spice. Recently I migrated back to apple music and media keys don't work anywhere. I already uninstalled both bearded spice and spotify. I also looked for "leftovers" from those two apps using `fd -i bearded` and `fd -i spotify` and didn't find anything. There are also no processes from either running.
