MoveEdge is showing “Unkown command”

For some reason MoveEdge is not working. I am getting an “Unknown command: MoveEdge” response when typed in.
When I use the button it reads “Unknown command: _MoveEdge”
I haven’t tried to use this command in a couple weeks and so I am not sure when it started to give this response, but I just update Rhino 6 this morning …
Is this just me?

Hello - I guess the SolidTools plug-in is not loading for some reason - se Options > PLug-ins and look for Solid Tools - make sure that is there, and enabled (check box)
