It seems that the Human UI LaunchWindow component breaks Rhino 7 (windows) when executing the new GrasshopperPlayer command in Rhino 7. To verify it I have created a .gh file that only includes the LaunchWindow component. I run GrasshopperPlayer, select the gh file, and Rhino 7 crashes.
This failure does not occur if, before running GrasshopperPlayer, I have run LaunchGrasshopper. So to verify it, launch Rhino, run with GrassopperPlayer a file with the Human UI LaunchWindow component, before launching Grasshopper.
I’ve read another topic about breaking Rhino when running its ScriptCompiler command from the Grasshopper menu, because of Human UI. Perhaps both failures are related.
It would be very interesting to solve them, because through the GrasshoperPlayer I can execute Grasshopper files under the friendly interface of Human UI, without having to display the Grasshopper window. This means that Grasshopper applications can be run as Rhino plugins, making life easier for users unfamiliar with Grasshopper. Any solution? Many Thanks!
