Hi,
This could be a wiring issue, an optimization bug (that should not happen when using out-of-the-box ESP-IDF) or a FLASH programming issue. First of all, please try simply pressing F5 to continue from the stop. Does the program resume as normal?
If not, please try creating and programming a basic “LEDBlink” project and then restart the board manually. Does the LED blink? If not, please follow this tutorial. If yes, please try disabling all breakpoints and try debugging it again.
