Editor is crashing when trying to enter play mode with terrain in view. This appears to only happen with XR + HDRP + Multi Pass, single pass doesn't reproduce the crash

How to reproduce:

1. Create a new project with 3D HDRP template
2. Go to Player Settings and enable VR support
3. Add the Open XR package in the Package manager 

## Enable OpenXR -> Mock Runtime

1. In the Hierarchy create a new Terrain

## Paint some terrain on the asset in view of the camera view

1. Enter the Play Mode

Note: The crash appears to be caused by the Camera. Disabling the main camera in the scene stops the crash from happening
