Write code in Arduino IDE; not uploading to nucleo-f446re

I'm using the nucleo-f446re board. I'm using the mcp2515, BTS7960, and nrf24l01 modules in this board, but I've been using the digital pins repeatedly due to my mistake. These boards and modules are intended to be used for data collection on the vehicle, but when applying external 5V power, I connected the jumper to the E5V position and used it well when uploading the code, I connected the jumper to the U5V. However, at some point, the code is not uploaded and errors are appearing.

해당 보드를 STM32CubeProgrammer에 연결해봐도 연결이 되지 않습니다

Sorry. Meant black lead to GND. One measurement from left pin, one from right pin of JP6

U4 looks from photo to have some pop-corning, and U3 might too

The picture's large and sharp, but you check if these are physically deformed too. Or get burning hot.
