Has anyone experienced a strange shadow effect when using volumetric fog? Does anyone know what causes it or how to fix it?

This issue occurs when I look up, down, left, or right it creates a shadow that ingulfs the whole screen. The only reason you can see the images below is that when I also move left, right, up, or down, the shadow refreshes, allowing visibility. This is why you can see the black shadow box in the middle of the screen—it’s formed by my movement. Otherwise, the image would be completely black, making it impossible to see anything.

In summary, when I move, a shadow appears that also disappears with movement. Initially, the shadow forms and can be shaped by moving it to the edge of the screen. It then refreshes and vanishes. If I do a full 360-degree turn, the shadow disappears but reappears after moving for a while or looking at something that projects a shadow.

I wish I could share a video, but as a new user, I can’t. And this issue is difficult to explain.
