Package failure UE12.5: Program.Main: AutomationTool exiting with ExitCode=1 (Error_Unknown)

Ok so I have error after package to Windows 64bit or 32bit. However I can “Cook Content for Windows” without problem.
The project was created based on Physics level from Content Example.

I tried to:

  • Resolve potential errors
  • Change build configuration from Development to Shipping
  • Turn off “Include Crash Reporter” because of the sentence in log that indicate it can be connected with CrashReport. However another, similar error occured so I think the problem is deeper.
  • Set Global Default Server Game Mode from None to one of my maps
  • Reinstall Unreal Engine Launcher, Reinstall UE4.12.5, Reinstall Microsoft Visual Studio 2015, Recheckout my project

One of my colleague can build project so it is probably local problem.

Last sentences of output log are:

Do you have debugging symbols downloaded for your version of the engine? They’re off by default when installing.
