How to reproduce:
1. Open attached project or create an empty project
2. Go to File>Build Settings>Player Settings>XR Settings
3. Enable both Vuforia AR and Virtual Reality Supported
4. Enter play mode

Expected result: Play mode works
Actual result: Unity crashes upon entering play mode

Reproducible with: 2017.2.0b2

Note: Vuforia AR was only introduced in 2017.2.0b2, that's why it's only reproducible on that version.
