STEPS TO REPRODUCE THE ISSUE

1. create new server on arcore cloud
2. wait until there are planes so you can place anchor
3. when anchor is placed i get error
   NullReferenceException: Object reference not set to an instance of an object
   GoogleARCore.Examples.CloudAnchors.AnchorController.b__9_0

I made no changes into CloudAnchorsExampleController.cs in _InstantiateAnchor()
and absolutely no change in AnchorController.cs
also there are no changes in LocalPlayerController.cs in function SpawnAnchor()

Also what is really interesting. I tried very old build where everything worked fine and it was also not working ... also i had installed older version on my other phone where it also worked, but now it is not.

I really need to fix this as I am making my bachelors degree thesis :/.

Thanks
