HELP!!! F405V5 FC SHORTS.

I was rebuilding my drone and now I have a short on the FC and have no idea how or why.

1. ⁠The ESC without the FC works fine with smoke stopper.

2. ⁠The FC is mostly plug and play except i have to solder a buzzer and leds. They were already soldered before and worked fine previously.

3. ⁠It works fine with USB - C.
