Had Arduino Nano Every working with step motor and relay circuit (as shown below), blew circuit while connected to VIN (+12VDC, 0-1A Meanwell) and USB, rebuilt circuit and cleaned it up, plugged into VIN and had no lights on the nano, meter tested 12.1VIN from VIN + GND pins.  Plugged in USB again to test (in addition to the VIN, which is also charging a step motor) and unit fried.

Any advice or assistance would be greatly appreciated.

Edit: added detail on power input
