Meerkat Demo - Empty Groom in UE5

Trying to view the Meerkat Demo in UE5, and the Grooms do not show up. It would seem as though they are there, but invisible or empty. I’ve seen others online open this project in UE5, so I’m curious what I could be missing here.

This is how the assets look when I open the project:

I have managed to solve the viewport banding problem with the meerkat scene.
Detailed description in this thread.

[end update 01]

Same problem.
If you open a new level the viewport looks like a disaster. Posterised and dithered.

Will revert if I solve this.
