Description

Attempting to launch a Development Server build of a project through the Visual Studio debugger hits a breakpoint when several Engine assets cannot be found or loaded. These assets are all reported to have been successfully cooked and saved when cooking content for Windows (see the attached Cook log), but the debug process does not appear to be able to find and load them.

The assets that are not being found and loaded appear to be Editor Only assets, which would not be available when running the project in the Development Server configuration.

Steps to Reproduce
  1. Create a new Basic Code Project.
  2. Add a Server target to the project.
  3. Build the project in Visual Studio for the Development Editor configuration.
  4. Open the project in the Editor.
  5. Cook content for Windows.
  6. Close the Editor.
  7. Set the configuration in Visual Studio to Development Server.
  8. Start a new debug session in Visual Studio.

RESULT:
A breakpoint is hit in Material.cpp on line 522, and multiple errors and warnings are shown stating that several Engine assets cannot be found or loaded (see the attached Debug log).

EXPECTED:
The project successfully launches for the Development Server configuration in the Visual Studio debugger.
