1) Does the USB port still work? You may need to shutdown + restart it to make it reappear again.
2) Does the Pico work in a USB port on another computer?
It sounds like you slipped when connecting wires and shorted together two of the power pins (or you connected something that was shorted). How much damage that did remains to be seen (I'm pretty sure I've briefly shorted one of my picos - power to ground - and it did the same thing as the original board did, ie, make the USB port non-functional until system restart, but otherwise not impact anything).
