Prime 4 plus jam issue

Hey guys, for these past weekends I’ve been running gigs on my prime 4+ and invited some Dj friends to play. I’ve been having an unpleasant issue: the browse knob and the buttons around (view, loads, back and forward) simply jam at some point and stop working until I reboot the system. This never happened before and the machine is a couple of months old only.

Is there anyway this is related to them using rekordbox sticks, or so?

I’m sorry if this had already came up on the forum, but I couldn’t find any topic related to this issue.
