Are you sure you're running the 'Espruino IDE' app and not accidentally running the Chrome Web app?
If you look in the console when running the Native IDE, it should say:
Initialising Serial
- Initialising Serial Chrome Serial
- Initialising Serial Chrome Socket
- Initialising Windows NUS BLE <-------------
- Initialising Serial Audio
But you don't seem to have that extra line. I just tried running the chrome app and it matches perfectly with your console log.
