XDJ RX3 - Slow, sort problems and freezing

I have the new RX3 all-in-one controller. Played all-nighter for the first time yesterday (on USB) and had some issues. First of all I can say that everything does not load super fast, this compared to the rx/rx2, this is mainly due to that small waveform in front of the song I think. I think you should be able to open a folder and scroll smoothly, but that's not the case. So very annoying. Well, if only it was just that... After playing for a while, the sort function suddenly doesn't work anymore, all numbers are mixed up and you can try to sort on anything, but this doesn't work anymore. In addition, I also had, and that is of course the worst, that I suddenly had no data left with my songs (no waveform, etc..., this with all songs), after which about a minute later everything froze and even the on/ off button no longer works, I had to pull out the plug. You understand that this is very painful in the middle of a set in front of a full house. My update is already the last one (1.10), so I don't know what to do now.
