3.3v(IoT0 & RPI connector) and GND Pins are Shorted (Heating Issue)


Hi All,
MangOH red board 3.3V(both RPI and IoT0) and GND pins are shorted, due to unexpected IoT0 Connector hot plug. But I am getting proper voltages on respective pins of both RPI and IoT0 Connector. The board is getting heated up high temp (U901 Component and around area) when we provide Power.
Board is crashing, and rolling back legato version.
Can anyone suggest what could be the issue?
Thanks in advance
