Crash when setting Project to only use Windows and DX11 with texture compression as BC7

When user sets their texture compression to BC7 while the project settings are set for Platform to only be Windows and use only DX11 this will cause any textures with this set to cause a crash when trying to open or right-click on.

Attached project and log/mini dump files.

NOTE: This can only be repro:ed on the publicly released versions of UE4 (after all files have been filtered out and everything has been packaged for public release)!

1. Start a new blank project (Blueprint or C++) with Starter Content
2. Go to Edit -> Project Settings, under Platforms -> Windows turn off all 'Targeted RHIs' except DirectX 11 (SM5)
3. Restart the Editor (important)
4. Open any Texture from the Content Browser (e.g. StarterContent -> Textures -> T_Brick_Clay_Beveled_D)
5. In the Texture Editor change the Compression setting (Details Panel) to either BC7 or BC6H (aka HDRCompressed)
6. Editor will hard crash, without crash reporter.

Results: The editor will close after this and after reloading trying to open the texture or right-click will crash

Expected: Should not crash.
