Ah, Here I am with the exact same problem. Here's what my deal is: This all started at the 2.8 update. I've factory reset it a couple times. I am using the factory power supply and it's been sitting on my pedalboard since day 1. I play in a cover band and our list gig before the covid shut down, it happened at least 2 times per set. Had to restart it onstage. I've noticed it will happen when in preset mode, snapshot mode, when i'm just playing and not touching anything, and it also happened when I was turning the knob changing presets. It will also happen if I pick up my pedal board and move it sometimes. There is no pattern here, it's completely random. I tried going back to 2.7 and it still did it. With all this extra time on my hands I sat down to see if I could capture it on video, and low and behold, first song in. boom. Getting pretty stupid at this point and want to chuck it out the window. Really don't want to send it in and pay who knows what, especially now that I've been laid off. Might be time to jump ship.
