DDJ800-Rekordbox - freeze signal

I have DDJ-800 and I'm having issues with the audio just randomly through the main speakers. I had a show on Satarday and at random times the output audio would just stop playing...

Waveforms and track were still moving along but I have to turn the on controler off.

I'm playing on a 2016 macbookpro, macOs Monterey.

 Thanks in advance.
