Hi everyone!
Thought the board is connected to the computer correclty and in the right bottom corner of the sketch there's written "Arduino Nano Every, ATMEGA328 on COM5", the port list is void and it can't compile.
I followed all the steps in the Arduino support (https://support.arduino.cc/hc/en-us/articles/4412955149586-If-your-board-does-not-appear-in-the-port-menu) but they didn't help.
I bought it by the arduino official store (Arduino Nano Every — Arduino Official Store) but I have the same problem with an Arduino Nano 33 IoT I bought on Amazon ( https://www.amazon.it/dp/B07VW9TSKD/ref=redir_mobile_desktop?_encoding=UTF8&aaxitk=535eaebbc3a0c765129fc4207309194f&content-id=amzn1.sym.6e03adfa-fa92-4923-8652).
I hope some of you will figure out how to solve that problem because I don't now wich way to turn

Thankyou
