🔧 Bug Fixes
- Fixed an issue which could throw an exception when subsystems were run in the Editor (e.g., for simulation or remoting). This could happen when a trackable (e.g., a plane or anchor) was removed. This did not affect Player builds (i.e., on device). This is an example of the exception and associated callstack:
- NullReferenceException: Object reference not set to an instance of an object
- Unity.Collections.LowLevel.Unsafe.AtomicSafetyHandle.CheckReadAndThrow (Unity.Collections.LowLevel.Unsafe.AtomicSafetyHandle handle)
- Unity.Collections.NativeArray`1[T].Copy (Unity.Collections.NativeArray`1[T] src, Unity.Collections.NativeArray`1[T] dst)
- Unity.Collections.NativeArray`1[T].CopyFrom (Unity.Collections.NativeArray`1[T] array)
- UnityEngine.XR.ARSubsystems.TrackableChanges`1[T]..ctor (System.Void* addedPtr, System.Int32 addedCount, System.Void* updatedPtr, System.Int32 updatedCount, System.Void* removedPtr, System.Int32 removedCount, UnityEngine.XR.ARSubsystems.XRReferencePoint defaultT, System.Int32 stride, Unity.Collections.Allocator allocator)
- ...
- Fixed a bug in `TrackableChanges` where `isCreated` remained `true` even after the container was disposed.
- Fix [XRReferenceImageLibraries](xref:UnityEngine.XR.ARSubsystems.XRReferenceImageLibrary) when duplicated from an existing reference image library. Reference image libraries are assigned unique GUIDs on creation, so if you created one by duplicating an existing library, they would have identical GUIDs. The actual reference image library used at runtime was not well defined in this case.
