FBX Export File Writing Plug-In Failed

I am trying to export a Rhino file to FBX , and everytime i got a file writinh plug-in failed , even if i have already deleted the bad object

Hi - does that also fail with a simple box in a new file from a factory-default template?
Have you checked if there are any plug-ins that are not loaded in the plug-in manager?
