DJM-A9 Master Output Cuts out

I'm hoping this will be an easy solution.

Today while editing tags in Rekordbox, the main output of my DJM-A9 stopped working.

No sound, no lights on the level meters.

The channel levels were still working, and when I used my headphones I could still hear sound through the cue.

The only fix was to turn the mixer off and back on. Then it was ok.

Currently using a 2022 M2 MB air using macOS Ventura 13.3.1

Firmware version 1.01

Thanks in advance.
