Non-editor configurations dont start/crash

Hi,

Though I could build finally all 4.12 source build configurations, I can start only editor ones. (Debug Editor, DebugGame Editor, Development Editor, etc)
All non-editor configurations starts, shows the popup then running around 40-50 minutes.
Despite I cooked the content in editor config, there is large runtime of these non-editor builds. If I pause in VS 2015, it stops on different locations of shader.cpp.
After 50 mins, Im always getting an assert in shader.cpp, then execution stops.
This is Im getting/found in log:

LogWindows:Error: === Critical error: ===
    
Assertion failed: InResource && InResource->Target == Target File:d:\Unrealsrc\Strategeist_UnrealEngine\Engine\Source\Runtime\ShaderCore\Private\Shader.cpp Line: 964

any idea what is wrong?

thanks,
Gabor
