Description

Editor crashes during initialization, but only on macOS 10.12, not 10.11.6.

Crash is due to a shader not compiling...

Update: Crash was not occurring on Nvidia or Intel. This was strictly an AMD issue.

Steps to Reproduce
  1. Download Game Dev Binary CL=3080242
  2. Create new BP or C++ Template project

Result: Editor crashes when initializing...
