Hey guys,
Not a problem,
Here is what I would like for you two to do.
1.) Create a new Project
2.) Delete the sky light and skysphere from your project so that the only light in the scene is the directional light.
3.) Delete the direction light that is called light source.
4.) Create a new directional light in your project
5.) If you directional is static or stationary then you will need to rebuild your light maps by clicking build in the main viewport.
There a few possibilities for what could be happening,
1.) Your lightmaps have not been rebuilt therefore causing the shadows not to be calculated in a render pass.
2.) There is a kind of issue with the skylight and skysphere overriding the shadows of your directional light.
I will continue to do more research on my end as you are recreating these steps
Thanks,
