"Get Assets by class" not returning anything, when applying a pak patch

I build a patch for our game. We have some blueprint code which gets a list of asstes by their class. This works fine in a fullbuild.

However, when i build a patch, and apply the patch pak to my original installation of my game, “get assets by class” will not return any asset.
Anybody has a clue? The assets in question were not modified inbetween the fullbuild and the patch.

Okay seems the Assetregistry takes its time to capture all of the data, so enforcing the scan of a very specific path where i have my assets in was the solution.
