XDJ RX2 Freeze

Hello,

last night i was playing with my Sandisk 128GB flash-disk.

Some tracks which week ago works normally doesn't load bpm and waveform, it says that USB 2 is full, but there is 15GB free. Track looked like loaded from folder like a normal mp3 with no rb analysis.

It played normally but when i touched beat jump music stopped and i need to unplug ac power.. 

1. Why is track loading with no rb analysis? ( In rb it shows normally )

2. Why RX2 completely froze? Last firmware update were in 2020..

Thanks.
