Why my Nucleo Board doesn't start the program when energized until I press the reset button?

I'm using STM Cube MX and Keil IDE in order to program my NUCLEO-F334R8 board, the problem is that I have to press the rest button every time I connect the USB port in order to start the main program, What am I configuring wrong? What can I do to fix it?

Greetings.

Should we all just guess? Try not reconfiguring the clocks, and see if it continues to run properly, do some debugging.

Try just building some of the examples under the CubeF3 HAL trees

What does "doesn't start" mean? How do you know it isn't "starting"? Is the board powered only from USB?
