Why does the viewport go black when I turn on a light?

Hello.
For a few weeks now, when you add a light, of any type, the viewport goes completely black.
This happens in texture shades mode. Obviously, it doesn't happen in wire, Iray, or filament modes.
In the render editor, I have dome and scene mode selected.
Do you know what I have set up wrong?
Thanks for reading.

Try going to Window>Preview Lights (or Ctrl+L) That should put light in place.
Ok. It worked. Thank you very much.
As for why, by default (you can turn it off in the Editor tab of Render Settings, in the general group) there is a Headlamp that shines from just by the viewpoint as long as there are no actual light nodes in the scene (environment maps and emissive surfaces are ignored). So adding a light switches it off, leaving only the new light. Turning off Window>Preview Lights tells the Viewport not to try to show how the active lighting works, instead using a light very like the headlamp - except that it doesn't render.
Man, I'm learning new stuff about DAZ Studio every day!
Thanks, Richard!
