That script relies on the GHPython component running in SDK mode. I’m not sure what the current status is with the [new script editor supporting this feature](https://discourse.mcneel.com/t/rhino-8-grasshopper-script-editor-design-feedback/163513/24), but either way I’d suspect it might require the component to be running IronPython (i.e. not CPython, which seems to be the case with the component in your screenshot).
