The Arduino IDE 2.0 is still a beta release and is so new that we haven’t done extensive testing to make sure all our EnviroDIY-related instructions, libraries, and sketches work perfectly.  So I would recommend you use the regular release of version 1.8.13 (available here: https://www.arduino.cc/en/software) instead of the beta version.
