I updated normal 3d assets to HDRP using the HDRP wizard. But the assets lost all colors and looks grey and washed out. What am I doing wrong?

I cleared the previous baked lighting cache. It seemed to have solved the issue. For now.

Edit: The lights are still not working in some indoor area. Which looks greyed out.
