Make sure that your walls/ceiling don’t extend past each other, otherwise you can get bleeding like that

Man, problem solved, thanks to you…look how it looks now.

Most likely the polygons on the back of the desk are in the same location as the polygons on the wall and it’s rendering illumination on the desk due to the Z-fighting
Move the desk away from the wall a little bit and it should be fine. You can also make an outer wall and that can help some areas.
