Buggy Shadows Using Nanite Unreal 5.3

Hey guys

So I’m running into a strange problem when trying to activate Nanite on my landscape. When I activate Nanite, it makes these weird shadow artifacts.

Also, when I attempt to sculpt the terrain after enabling Nanite, it seems to just disable the Nanite completely (however the Nanite setting is still ticked under Landscape’s detail panel).

I’m honestly at a loss as to why this is happening. I’ve tried a few fixes online, but nothing seems to be working. Has anyone else perhaps encountered this issue and found a fix for it?

Here’s a very short video showcasing the problem:

Any assistance in this regard will be immensely appreciated!

Kind regards
