Result:
Crash while compiling modules for the project
Fatal error: [File:d:\Builds\Release-4.18\Engine\Source\Runtime\CoreUObject\Private\Templates\Casts.cpp] [Line: 10] Cast of nullptr to Package failed
Expected:
Feature pack is successfully added to the project.
The only feature pack I hit this with is the C++ First Person feature pack. Crash looks like it occurs while trying to compile the modules for the project. I noticed that even though this crash occurs, a lot of the source and header files for the feature pack are added to the project. When I noticed that I opened the project and PIE-Viewport. Only issue was the projectiles were not rendering. I did see the physics/collision of a projectile hitting the cubes in the map.That being said, the header and source file for the projectile were missing from the C++ folder in the Content Browser and the Source folder in File Explorer.
Another anlalyst repro'd this on a binary build while they were set up for our normal workflows.
