Never Cook Fix
If you are setting up Directories to never cook in your Project Settings, you might get errors because your assets which are being cooked reference assets excluded from cooking. It might also give you errors when you're trying to simply save such assets.
This fix prevents any errors related to this problem.
It is especially useful if you're using Template Project because that project has all unnecessary directories set to Never Cook by default.
Installation
Go to your Unreal Engine 5.6 installation folder (by default it's C:\Program Files\Epic Games\UE_5.6)
Extract Engine folder from the archive here. It should prompt you to replace three files.
