I have installed pico-go extension in VSCode. When I do any View>Command Palette>Pico-Go > Help > Show Pico Pin Map... I always get Command 'Pico-Go > Help > Show Pico Pin Map' resulted in an error (command 'picogo.extra.pins' not found).
I get a similar error for any pico-go command. I have installed different versions of the Pico-go code, did restart after each and the problem is exhibited in all the versions I have tested. Pico-go states that it is dependent on Python 3 and Python3.9.1 that is installed and running in VSCode.
I have the same problem using CircuitPython commands on both systems. The Dependencies list includes Python and Juypter which are both installed.
I have a second system that has pico-go installed and it works properly. I do not know how to isolate what is wrong in the first system.
Even if I get this problem solved the getting started code
from machine import Pin
import time
pin = Pin(25, Pin.out)
while True:
    pin.toggle()
    time.sleep_ms(1000)
fails with
  File "e:\code.py", line 1, in <module>
    from machine import Pin
ModuleNotFoundError: No module named 'machine'
