DDJ SX-3 Audio suddenly stops when playing music

Hello! 

So the problem I have is a common issue, I've spoken to other djs who also have the same problems. It is very simple, but very strange and irritating. So, for example, when I am playing a song on my Serato DJ Pro, if I try to search something in safari, open App Store, or sometimes search in finder of my laptop, sound stops. Everything on the controller like lights and indicators are working, the serato as well, the waveform is moving, but with no sound. It looks like something with the sound card happens and it makes the system confused which sound card to use (the laptop or the DDJ-SX 3). I am using Macbook Air 2017 13 inch with Intel Core i5 and 1.8 ghz processor. I was playing on Catalina, then Monterey, and the audio driver is 4.0.0. I have tried many things like reinstall the mac os, change the cable, update everything to the latest version, smc  chip reset, another usb ports, nothing helps...
