In Rhino for Windows you can disable a Rhino plug-in by:
Start the
Rhino application with the
Safemode shortcut
Type the Options command
Go to the Plug-ins page
Select the filter Plug-ins that do not ship with Rhino
Uncheck the enable on the plugins your suspect or all.
Close and restart Rhino normally to test.
Report your crashing to the offending plug-in developer.
Do you need Delete a Mac Plug-in instead?
