Light Index out of Range

When I attempt to use the sun panel in Vray/Rhino, it says “Rhinoceros 6: Delete Light - Light Index out of Range.” The sun panel does not open, but it does seem to add a directional light in vray which cannot be selected in the rhino workspace.

Any help is appreciated.

Did you figure this out ? I am having the same issue. Thanks

I’m also seeing this issue. It’s a Vray issue, as it is resolved when disabling the Vray Plugin.
