Numpy has stopped loading in Rhino 8.1

I’m not sure if this is due to teh 8.1 update or something else in my config, but importing numpy into a python 3 script in Gh has stopped working

update, I’ve tried uninstalling and reinstalling Rhino 8.1 from scratch and still have the same problem

ah ok…

Tools> open command prompt > Reset Python 3 (CPython) Runtime

has to be engine not just runtime
