that's a serious short, yes, if the resistance between them is zero (or close to it). check the 5v rail.
I removed the RT8288, and now the 5V rail is no longer short to ground. However, I still can’t power the board over USB, I only get around 13mV on the 5V rail. I’ll check around some more and see what I can find. maybe a resistor is faulty.
next thing to check will be the SY6280 which is a current-limiter IC. datasheets and schematics: https://hands.com/~lkcl/eoma/microdesktop/
