    In Unity Editor 2022.2.10 with AR Foundation 5.0.5 using XR Simulation, when calling ARSession.Reset, I get the following error:

    NullReferenceException: Object reference not set to an instance of an object
    UnityEngine.XR.Simulation.SimulationPlaneSubsystem+SimulationProvider.CreateVoxelGrids () (at ./Library/PackageCache/com.unity.xr.arfoundation@5.0.5/Runtime/Simulation/Subsystems/Plane/SimulationPlaneSubsystem.cs:366)

    Thanks for the detailed bug report @ROBYER1. We'll take a look at this for our next patch release (a few weeks out). 5.0.5 was otherwise a pretty small release and you should be able to work from 5.0.4 in the meantime. Apologies for the inconvenience.
