Going from USB audio device back to kit breaks entire system

Can anybody confirm this before I report it on Github? Going from V5.1 kit to USB audio device works fine (First select custom kit, then audio device). Going back to the kit crashes the entire system to where it won’t boot at all and I have to reimage. This is on the latest Vangelis. I tried it with both a Tascam 16x08 and Focusrite Scarlett 4i4 (as Generic USB Device).
