Problem with MicroPython v1.9.1-394-g79feb956

I am unable to import network on the build below.
Have tried erasing flash and reloading xx.bin
Is this a problem or is it just me. Thanks

The above works here on an Espressif ESP32-DEVKITC with ESP-WROOM-32. What hardware are you using?

Tried several times with no luck but then tried with MicroPython v1.9.1-395-g381bb7e9 and it works fine. I am using a cheap Chinese board with ESP-WROOM-32. All OK now.... Thanks
