When I package this project, it shows me: UATHelper: Packaging (Mac): Cook: LogScriptCore: Error: Script Msg: A null object was passed as a world context object to UEngine::GetWorldFromContextObject().

In addition, when I open packaged file of this project, it couldn’t be run completely, specifically stoped at initializing movie player.

Therefore, could you please tell me whether there are connections between these two errors and how to solve these?
Thank you very much.

Check AIController if you had one. I experience same problem with AIPerception component when I compile AIController blueprint and packing a project: "Error: Script Msg: A null object was passed as a world context object to UEngine::GetWorldFromContextObject()" after compiling AIController blueprint with AIPerception component - AI - Unreal Engine Forums
It seems that this is an engine bug.
