Master Volume Cuts off in mid set - DDJ FLX10

I bought DDJ FLX-10 Two days ago. Took it to the event and it played good for 2hrs or so then all the sudden while mixing the music Sounds cuts of and I don't see Master channel pushing out anything anymore. (Master Level light's went out).

I did had DDJ-1000 before this and everything works smoothly with the same Rekordbox Version, and same computer.

I tried restarting controller (doesn't help same issue.) I tried restarting the Rekorbox did help, other times I had to restart the macbook. I even got controller replacement.

For the reference: I video Dj with High Quality Streaming.

Using: Mac Book Air 15in M4 2025

Have no issue with any cables or USB. my Buffer Size is: 96, everything is up-to-date including macbook, controller, driver, and software
