Who writes this tutorials/instructions ?
I don't have RPi or Linux and I have interest installing one since there is a Windows instructions here https://www.zigbee2mqtt.io/guide/installation/05_windows.html
Followed step by step 2x fresh install and not working. 2nd day same steps same result.
I can open COM18, see the boot, able to flash from python or web so unsure what is missing...

$ npm start
