Hi @pavan_p,
There is an error message in your console which indicates a problem in the Unity editor. Please go to Window > Layouts and select “Default”. If you created your own layout, remove that, select “Default”, rearrange the windows and save it again.
Regadring the lighting, please go to Window > Rendering > Lighting Settings. At the bottom of the Inspector, click on “Generate Lighting”. You could also try to disable “auto-generate lighting”.
Did this help?
