Weird shadowing that appeared out of nowhere.

I was working on one of my projects for about 2 hours, everything looked great and I saved and took a break. When I come back I find that these opaque shadows appeared without changing the skylight, light source (sun) angle, or ambient occlusion. Increasing the skylight intensity doesn’t help and AO isn’t the problem. If you have any solutions I would love to hear them. A screenshot is down below.
