I suddenly got an error on opening Grasshopper that:
External file loading failed. Grasshopper may not run correctly after this.
System.IO.IOException: The directory name is invalid.
With further details as in this image:
On closing this, Grasshopper opens, but none of the plugins load, and the palettes are all empty:
And if I try to load a GH file, it can’t recognize any components
I have tried getting rid of any .gha files anywhere besides for the Libraries folder, restarting my computer, repairing Rhino, and reinstalling Rhino, all to no avail.
This error seems to have come about when I was having issues with a conda environment (accidentally uninstalled compas_fab while trying to uninstall and reinstall pyserial, tried to revert to a previous revision, but files were missing, etc.).
Is it possible that conda environment issues could have messed up grasshopper? I have since deleted the messed up environment and created a new one (with compas and compas_fab installed), still having the same issue.
Let me know if you need any further info!
