Dedicated Server with critical error EXCEPTION_ACCESS_VIOLATION

After i followed the UE4 guide : Setting up Dedicated Servers, i can get folders and files that are packaged by UE4 engine. And i make shortcut FPSServer.exe with “-log” tag as well. But the problem is happened when i run it. Many text lines appeared and suddenly ware closed before i check what logs on the Prompt. Fortunately, i can stop scrolling it clicking Mouse1 on Prompt screen.

=== Critical error: ===
Fatal error!

It is only what i just have known about EXCEPTION_ACCESS_VIOLATION is about Pointer problem. But i don’t understand why my game is working well on UE4 editor with using multiplayer option. Could you please help me to solve this error and let me know why it is happened?

In my case, the reason of this is the Level include AActor instances. I remove them and my dedicated server is working well.
