XDJ-RX3 Random freeze or emergency loop

Hello, i recentely bought a rx3 and It immediately started freezing randomly, It also happened to not ready correctly usbs for a second, so the console goes into emergency loop but then ready those again a fee seconds later all by It self. I checked for firmware and quickly updated It, and changhed also the usbs, Sandisk Extreme (FAT32). THOSE ARE NOT FULLED UP WITH MUSIC. It's stile freezing, don't know what to do
