Physical light sources not working

[Ngan30955496i9fg]

I'm trying to add lighting to my retail store project. When I started, I added some physical spot light and they worked well. But later on, when I try to add area lights, they emit no light. I tried to change the temperature, intensity, exposure etc but nothing happened. I even copied and pasted the spot light that I first added but the pasted one also doesn't emit light. Could anyone tell me what the problem is and how I can fix it? 

Below is a screenshot of my scene. The emitting light sources are what I added first. None of the other sources are emitting light.

Dose this happens after latest update?

I think so, because I just downloaded Stager a few days ago. I tried exporting the objects without the lights into a new working file and when I added the lights, they work just fine. But after adding the 12th light, the following lights don't work again. I deleted the first 12 lights and then 13th and 14th begin to work perfectly. So I suppose this is a lighting limit in Stager where 12 is the most I can have.

Not aware abou tlmitation, but may be it can depend on hardware or scene complexity  I am able to add more that 20 lights, from which 15 is Spot lights and I am able to change color, expousure. The exact answer we can expect from the Stager team.

Yes, I think it's the limit on my device. I'm using a 2021 MacBook pro 14 M1 pro 14GPU/16G/512G, which is not optimal for 3D stuff.
