XDJ XZ frozen while using pitch effect

I just received XDJ XZ after 2 months of waiting while on back order. Been using it for about a week and running firmware 1.10. All of a sudden last night while usiing the pitch effect and changing the time parameter the machine froze up. Could not switch to another effect, menu buttons would not work and faders were unresponsive when you move them. Also some lights stop illuminating and master decibel lights were lit partially.Only thing I could do was play and pause. Im using a sandisk extreme pro ssd stick 256gb, formatted as Fat32. The resolution was to reboot the xdj xz... What gives??? Really would hate to start having problems with this thing already!
