LogStreaming: Error: Couldn’t find file for package /Game/Crowd/Character/Shared/MaterialFunctions/MF_NormalStrength requested by async loading code. NameToLoad: /Game/Crowd/Character/Shared/MaterialFunctions/MF_NormalStrength

so i went to this location fixed it replacing the file

That error usually means the file is missing or didn’t migrate properly. Easiest fix is to re-add the asset (from backup or the original marketplace/plugin it came from) and then run Fix Up Redirectors in your Content Browser. After that, do a clean build and the export should work fine.
