Hi, I have found a solution for this:
my situation was, that this error message was showing and it results in corrupted nanite meshes - distorted - similar to proxy meshes.
Occasionally there was another error related to Derived Data Cache.
I tried to delete DerivatedDataCache from project (as well with Binaries, Intermediate and Saved) and rebuild the project, but with no working outcome - error was still spamming the output log.
But there are other DerivatedDataCache - not for project, but for editor installation itself. My was at C:\Users<user>\AppData\Local\UnrealEngine (Note: AppData may be hidden)
I deleted this folder and this fixed issue. Side effect is, that you will loose all your editor settings like, window layout, projects in launcher view, etc…
