Cannot build project

So i’ve finish the stuff and i build the lightning and then, it shows this error.

I need help, someone pls tell me what is going on? No more space or what?

First add a light mass importance volume in your scene , very important when building lighting you can find it in modes , second remove the foliage from the lighting either by moving into a different level or making it movable , the issue you are facing is of memory so ram issues. Other than increasing your ram you can try baking lights by dividing your assets into different levels .

Thx 4 the answer, it works.
