I've had problems during installation probably due to firewall/proxy/network protection, so I managed to install from command line as specified in Installing the nRF Connect SDK.
All good so far, but know I have problems when starting development from VSC: when I try to "Create a new application" from the "NRF Connect" VSC menu and try to "Copy a sample" I don't get any sample.
I simply get the "No samples available" message in place of the sample list.
Also, if I try the "Browse samples" menu voice, I get the following error messages:
[west]: FATAL ERROR: failed manifest import in zephyr (zephyr):
