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:
# Create a new project with 3D HDRP template
# Go to Player Settings and enable VR support
# Add the Open XR package in the Package manager 
## Enable OpenXR -> Mock Runtime
# In the Hierarchy create a new Terrain
## Paint some terrain on the asset in view of the camera view
# 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
