Fatal error: [File:D:\Build\++UE4+Release-4.15+Compile\Sync\Engine\Source\Runtime\Engine\Private\GlobalShader.cpp] [Line: 353] Missing global shader FPixelShaderDeclaration, Please make sure cooking was successful.

This issue has not been fixed in 4.17 as described in the Bugtracker. I just had exactly this issue with my packaged build and re-enabling the VR Plugins fixed the crash.
