(Moved to the V-Ray section of the forum).
SketchUp does not render any lighting other than the global or viewer lights. To see the effect that these lights have on your model, you need to view it in V-ray.
I’m not sure if it’s the issue, but it is possible in V-Ray light settings to make a light source not visible to the camera; you can see the effect of the light, but not the source.
Exported the whole scene to a new file (new scene) All OK
I’m still a beginner myself and haven’t mastered light sources yet.
