A lot of people have reported this problem over the last year or so. Here’s a recent one:

Unreal Engine 5.5 Materials Turning Black

I also have this, I have no idea what causes it. There’s a very definite hitch ( maybe 2 secs ) and then something in the environment will be black. No errors in the log. I also see people who have this after packaging. What’s your GPU?
