Summary

I tryed to add DataLayers to reduce the memory load in the game.
For this i added DataLayers to my map and followed this Tutorial:

But after adding all of those and adding trees and sones and everything else to the DataLayer it crashed with a validation error and since then i tryed to delete those bindings and removed those DataLayers but i can’t remove the WorldDataLayer and that gives me the last validation error.

I would try…

Make a snapshot just in case… then close UEFN and use windows explorer to manually delete …/6/SX/5X6MCAGRUEK5PRWBOMPU71.uasset from your project folder.

Tryed to delete it and now it wants it back:

AssetCheck: Error: [AssetLog]  /.../...: References /.../__ExternalActors__/.../6/SX/5X6MCAGRUEK5PRWBOMPU71 which does not exist. (FortValidator_IllegalReferences)
AssetCheck: Error: [AssetLog]  /.../...: References /.../__ExternalActors__/.../6/SX/5X6MCAGRUEK5PRWBOMPU71 which does not exist. (FortValidator_IllegalReferences). (FortValidator_WorldPartitionActors)

I solved it.

Solution:
I went in to my projects folder in documents and saved the folder somewhere else.
After that i downloaded the project again from epic (sync the map from uefn) and that was a older version of my map where that datalayer file was not broken.
I started uefn and i could indeed launch a session. (validation passed)
Now i deleted the 5X6MCAGRUEK5PRWBOMPU71.uasset and replaced every file in my projects folder to get back where i was before.
That solved the issue for me.
