Very black shadow and black squares. what I do?

good afternoon. I have a problem with a project, it suddenly closed, and when I reopened it, the shadows are very black in one part of the project. It had raytracing activated and moving lights. I do not know what to do. sorry for my English.

I tried to rebuild the lights, turn them on and off again, but it’s still the same as before

Change Exposure setting

It looks a bit like you’ve lost your skylight, do you still have one? Is it set to 1.0?

Thanks for answering, I was able to solve it, it was neither of those two, in the end I decided to turn off the geometries one by one, and I realized that a geometry caused all that error, eliminate the geometry and everything already works.
