The error message "A fatal error occurred: Failed to connect to ESP32: No serial data received" typically indicates that the computer running the Arduino IDE is not able to communicate with the ESP32 board via the serial port. This can be caused by a variety of issues, such as a faulty USB cable, incorrect board settings, or a problem with the ESP32 board itself.
