Why is my HDRP scene so bright?

In my scene is no directed light, only small point lights, but my scene is too bright,
Especially when the camera is looking down.

What is that setting, that makes my scene too bright?

Add a Volume Component to your scene and adjust the weight. I fixed it by myself.
