CreateExport failed to load Outer for resource 'AssetImportData'


I’m running on a mac Unreal 18.3, when I tried today to open the project I’m working on a lot of the textures and materials didn’t load and received a message log with a lot of errors “CreateExport failed to load Outer for resource”.

I tried everything I found on the web but nothing worked. I even tried uninstalling completely Unreal and Epic Games, but it didn’t change anything.

Please, let me know what I can do to fix this.


If you got something like this try to migrate your whole project to a new one.
