PackagingResults:Error: Error Unknown Cook Failure
Well, looking to your log I have found this: Error Wrong class to spawn 'None' in Construct Object from Class from Source: /Game/Untitled.Untitled:PersistentLevel.Untitled
Can you check if there is any blueprint (even level ones) trying to spawn 'None'?

The reason is your blueprint has compile errors, you need to fix the blueprint compile errors first.
