Opening an GRASS addon from the terminal on Windows

Just to check before filing a bug/feature request: on Windows, when trying to open Python addons from the terminal, I get the error:

“unable to fetch the interface description for command ‘’

The python file is there, and launching the addon from the console works.

I thought launching an addon from the terminal always worked, but perhaps I am mistaken.

Under what conditions? In the 8.5 release candidate or the 8.4.x? Are you updated? Is the addon a new install/new download?

Both version 8.4.1, installed with the normal installer and 8.5 with osgeo4w installer. All completely fresh install on a new Window 11 install.

8.5 is out on osgeo4w now?
