Sometimes it's dark when running standalone

Sometimes it’s dark when running standalone. Not always. I think it only happens 10% of the time when I run standalone. I think it happens at least once a day. It seems like something isn’t loading properly.

It usually looks like this:

But sometimes it looks like this:

I have only the light of the sky.

And it doesn’t move. It’s stationary.

I have not made any changes to the postprocessing volume either. I think it has all the default options. I have it since version 4.27 (it’s the one that came in the shooter example)… I have never changed its configuration.

And i’m using Cinematic, in the editor and in standalone too.

I have not tested the shipping versions.

Does anyone know what the problem could be?
Thank you so much!!
