I moved your topic to a more appropriate forum category @jesu_juku.

The Nano ESP32 category you chose is only used for discussions directly related to the Arduino Nano ESP32 board.

In the future, please take the time to pick the forum category that best suits the subject of your question. There is an "About the _____ category" topic at the top of each category that explains its purpose.

Thanks in advance for your cooperation.

Hi @jesu_juku.

Please try this:

  1. Select Sketch > Upload from the Arduino IDE menus.
  2. Watch the black output panel at the bottom of the Arduino IDE window until you see this text printed:
    Connecting...
  3. Press and hold the button on your ESP32 board.
    ⓘ if your board has multiple buttons, you might have to do some trial and error to determine which is the one you need to press.
  4. Wait about one second.
  5. Release the button.

The upload should now finish successfully.

I don't see any error there.

This output indicates you have clicked the "Start Debugging" button on the Arduino IDE toolbar. Did you intend to use Arduino IDE's integrated sketch debugger?

If not, then you should avoid clicking the "Start Debugging" button.

If you did intend to use the debugger, you should wait until after you have solved the uploading problem. Once that is solved, I can try to provide assistance with using the debugger.
