A crash occurs when setting the WorldGridMaterial from the Engine Content to the Unlit Shading Model and pressing apply.
1. Open any new or existing project.
2. Open the WorldGridMaterial from the Engine Content.
3. Set the Shading Model to Unlit.
4. Press Apply.
Outcome Crash occurs after applying the changes.
Expected The shader is saved using the Unlit shader model.
