I’m just bringing your other topic here as it’s the same board and the same fault so it’s easier for others to follow
If you suspect the USB port, visual inspection first, look inside and make sure none of the pins are bent and make sure the stem hasn’t snapped or feels loose, then I would verify you have continuity to the relevant points (using one of the many diagrams here) using a USBC breakout board, if all lines have continuity then the USB is likely fine
As for the error, remove the M92 IC, ensure the pads on the board have no bridges and it’s clean, power on the console with battery (don’t connect USB) and see if the error remains, if it doesn’t then it was solely related to the M92 IC… if the error remains with the M92 IC removed, then go ahead and remove the P13 IC next, same deal, check no pads are bridged and the board is clean, if no error then it was the P13 at fault
