Print options gone

I’m on 6.19.
I was installing some AC hatch patterns, then decided to cancel. Rhino hung up so I tried to tried to shut down via Task Manager. It eventually did. After restarting and opening the autosaved file, I went to print. I get this error.

Hello - open Options > Plug-ins page and look for the Renderer Development Kit (RDK) and Renderer Development Kit UI plug-ins - make sure they are enabled, then right click on each and choose Load plug-in. Any better?
