Hi, sorry if I'm bothering you again, but I could never get my system to work properly in the end and then I didn't have time to dedicate to it, i still get that very same error and i don't really know what to do. Do you have any idea? I also tried with an Elegoo Uno, so the board is not the problem because I'm getting the same error. Also, the Arduino IDE can correctly access both the devices, so I reallty don't know what else can be done.

Fun fact: resetting the Arduino by the reset button enables the 'identify' effect (flashing 2 times, all leds white). But after that I can do nothing and the error message is still the same.
