Hi Joshua,
Unfortunately, I tried taking a look at the Aftermath dump you attached. Still, as you already mentioned, since there are no shader debug symbols available, it is impossible to tell the cause of the crash. To add shader PDBs to your build, you will need to set the following options in your BaseEngine.ini and cook your game:
r.Shaders.Optimize=0 r.Shaders.Symbols=1 r.Shaders.SkipCompression=1 r.ShaderDevelopmentMode=1
The cook process should then produce the PDBs under the project directory inside <path to project>/Engine/Saved/ShaderSymbols. Just so you know, this can make a large amount of data, so do this sparingly to save disk space. If you then point Aftermath to that directory, you should be able to view the associated shader source code inside Aftermath. Feel free to let me know if you have any questions around this.
Cheers,
Tim
