Is it possible to package Blueprint based project with a source build of the engine?

I am using a source build of the engine with all build targets compiled (development, shipping, etc) . If I create a Blueprint based project using this build, and create a package build of said project, the build and package will complete without any errors or issues. But when I go to the package location there are some missing files and the available executables will not launch.

For example, if I create a development build of a blueprint project it will contain an UnrealGame.exe executable under the generated Windows/Engine/Binaries/Win64/ folder. The .exe that is usually generated under Windows/{MyProject}/Binaries/Win64/ is missing. The myproject.uproject that is usually generated copied is present in a shipping build, but not a development build. At this point I’m wondering if Blueprint only projects are not meant to be used/packaged with source builds of the engine?

Thanks

I found that I had a call to FPaths outside the class contructor. This call to FPaths was causing the crash in Blueprint based projects. It looks like the crash was happening before the log system could initialize. I assume that’s the case since no log files were ever produced.

I found this by launching the produced package in visual studio while targeting the package .uproject file. The call stack was able to then point me to that FPaths call.
