I have a similar issue in a basic architectural visualization level I’m trying to build. I created a rectangular box room, and applied the sandstone material. The next time I opened the project (in 4.24.2), the room was completely black on the outside, and probably inside though I didn’t check. After a bit, the shader compiling started, at around 7-8,000 or so, and took a while to finish. Then all but one surface was the sandstone material, all in a really basic level setup without even a directional light or point/spot lights.
Try rebuilding lighting, reflection captures, compiling shaders. As for the perspective of the camera in the first picture, I don’t see what’s wrong with it.
