Reply To: "Type with name could not be resolved" for classes that definitely exist

Hello again and thanks for the extra info.
Just to rule out a few things, can you please try opening up “GraphAssetPostProcessor.cs” file and comment out the 2 calls made in the “PreInit” method, like this:

1 2 3 4 5 6 7

[InitializeOnLoadMethod]         static void PreInit() {             // EditorApplication.delayCall -= Init;             // EditorApplication.delayCall += Init;         }

This will remove some secondary features (nothing will break), but may also be the cause of the problems you are facing.
Please try this temporarily and let me know.
Thanks!
