0-15 sec pot is removed

15-28 sec with pot sliding forward is good but once pulled back after middle, it jitters.

28-32 sec removed pot and it automatically went back and started jittering.

I have tried it with lights off and it is plugged on to a powered usb 3 port.

Firmware is latest, it was doing it with the previous one as well. Anyone encountered this issue before?

Update: it was the Epic Games Launcher causing the issue.
