Feedback Unity Freezes when TryRemoveReferencePoint (AR Foundation)

Each time I racyast and touch I can create a new ARReferencePoint.

But if I add to remove the previously added ARReferencePoint, Unity freezes indefinitely.

I am using ARFoundation samples without changes except for XRRemoting.

I first add ARRefPoint:

Then I create a new RefPoint and remove the previous one: At line TryRemoveReferencePoint Unity freezes:


I also tried moving TryRemoveReferencePoint inside and outside the raycast condition and at the end of Update() with a bool but in all cases Unity freezes with no error messages on console to look into.

Anyone has any tips or having this same issue?

Thanks a bunch for your help !
(Tested on Unity 2019.1.1f1, ARFoundation 1.1.0 preview.6, lwrp 5.6.1, XRRemoting 0.0.1 preview .10)



Sample code:

sample code using ARRemote:
if (m_SessionOrigin.Raycast(ray, s_Hits, TrackableType.PlaneWithinPolygon))
if (spawnedObject == null)
{
spawnedObject = Instantiate(m_PlacedPrefab, hitPose.position, Quaternion.identity);
spawnedObject.transform.SetParent(m_CurrentRefPoint.transform);
Debug.Log("Instantiated");
}
else
{
spawnedObject.transform.position = m_CurrentRefPoint.transform.position;
spawnedObject.transform.SetParent(m_CurrentRefPoint.transform);
Debug.Log("Current Ref Point: " + m_CurrentRefPoint + " Removing RefPoint:" + prevRefPoint);
m_ARRefPointMgr.TryRemoveReferencePoint(prevRefPoint);
}
prevRefPoint = m_CurrentRefPoint;
