Rendered viewport completely black

Hi,

My rendered viewport is completely black. No matter how many lights I add or if I enable or disable lights in rendered viewport shading, there’s no effect.

Blender 5.0.1, render engine Cycles.
World strength = 0 (so that i can see the effect of lights)
Light source 1000W. I tried 1 trillion and other.
Camera is not clipped.
viewport shading >> Scene Lights and Scene World enabled, compositor disabled, render pass Combined.
I tried scaling objects and scene.

Crazy, thanks for the help.

since this could be many different reasons, please provide blend file (you can upload to any cloud service and copy link), so we don’t have to guess around.

found it, selectability and visibility >> lights were turned off. Thanks so much!
