"Unable to render. No renderer available." ??????

Fauvist

So, like, after something like 10 years of making renders - I get this error message pop up when I try to make a render: Unable to render. No renderer available.

I haven't changed anything since I last rendered.  I'm stil on a MacOS Catalina 10.15.7.  I'm still using DAZ Studio 4.12.1 Beta.  I've been using this exact set up for the last few years.

Suddenly Daz Studio says there is No renderer available.  Why?  What happened to the renderer?  Where did it go?  Since 2 days ago when it worked fine?  It just spontaneously disappeared without any assistance from me.

How do I fix this?
