You have global illumination disabled and as a result you cannot shadow the skylight, you have no way of fixing this other than using some form of GI, either Lumen or Lightmaps, or by doing what @MostHost_LA said above and using transition regions to fade out the skylight intensity.
I’m not talking about the exposure (ev100), I’m talking about the local exposure settings. You have extreme halo’ing around the lit regions of your scene.
