Thanks for the report @gillesF78!
It's possible the ESP32 in the Arduino Nano is newer than the last release of Mu was able to detect.

Could you try one of the tests installer for your OS from this link? It's not an official release, so it's not signed, but it contains the latest updates from this project:
