I shorted my Pico, anything I can do?

Even red LED doesn't blink when I connect Pico to PC. Can I replace broken components or there is no point and I should wait for the next batch? If there is chance to replace components, how can I find burnt one? I have multimeter and I can recognize only surface mount resistors and capacitors.
By visual inspection component labeled as C106L seems little bit off and when measuring resistance with multimeter it doesn't show anything. But I can't be sure as my multimeter is acting weird lately (random values when there is no contact, going to buy new one).

What actually happened when you shorted it out?

First step is I'd plug it in and check the voltage between GND+VCC, and GND+3.3v.

If those aren't around 4.5v and 3.3v then my guess is it's the USB power diode. It's the small component nearest the USB connector with S4 written on it - it should be pretty easy to replace. If you're only ever going to be running the board off of USB then you could actually short it out.

Yes, it seems it is just USB power diode. I'll short it while I go and get new one.
Thank you!
