The file needs a big dose of debugging.
See attached. It is now working (get results) but i suggest to revise the geometry from it’s base.
I tried to see what happens when you disable the shades and the windows. The problem is in the windows. Some faulty or Null geometries are created. I culled them and connected the geometry separately, as you can see in the yellow group.
Sure it helps but i assume this can’t be the proper solution for you.
Again: spend some time checking the base geometry.
