Hi @aliccey. Please try this experiment and then report back with the results:

:exclamation: This procedure is not intended to solve the problem. The purpose is to gather more information.

  1. Connect the Arduino board to your computer with a USB cable.
  2. Press and release the button on the Arduino board that is marked "RESET".

Now please reply here on the forum thread with the answers to the following question:

  • Did you see the LED marked "L" on the board blink immediately after you released the "RESET" button?
