Grasshopper hangs on load

Hello

My Rhino 8 Grasshopper always hangs for a minute on first startup while showing the following :

and simultaneously Rhino status bar (greyed out because of window freeze):

(Obviously no gh script loaded at that time).

Does that happen to someone else?

Does anyone know the root cause? I have the impression that the hang is getting longer each time…

Hi Raphael,

This is most likely a conflict of some sort.

A quick quick troubleshooting method is to start Grasshopper with the GrasshopperLoadOneByOne command.

or

  • Navigate to %AppData%\Grasshopper\Libraries and temporarily remove all third-party plugins
  • Restart Rhino and reopen GH to see if the hang persists
  • Re-add plugins one by one to identify the culprit

Thanks!
Took me some time to find how to use GrasshopperLoadOneByOne efficiently. Had I known that it copies the last accepted (Yes button) plugin’s path to clipboard would have saved me many tries…

In the end it appears that :

The Python & Markdown loading is triggered by byRhinoGadget (including latest by PackageManager), and takes 10-20s to load.

The hang actually happens a few plugins later, namely the bundled GhPython, which takes over a minute to load!

But after uninstalling byRhinoGadget… GhPython loads in a few seconds. So the former is indeed the culprit in its impact on GhPython.

Why exactly, I don’t know.

Well that wasn’t the end of the story. After a restart, Grasshopper still hangs about a minute after I say Yes inGrasshopperLoadOneByOne for GhPython

@Japhy Are there any known issues for GhPython ?
