Hello I have this machine stopped on the 5v 0.09A on the usb ports on the right and 20v 0.02A on the usb ports on the left, Also the voltages wrong at U7800 are unstable or they are in loop between 0V and the nominal value PPBUS 12.57

You have some problem on the left USB-C area.

Do you get stable 20V on right side, even with U7800's fluctuating voltages?

Yes, that's right

Compare diode mode readings between left/right channels...
