This error occurs randomly, sometimes within a couple of hours of running the application, sometimes, over a day. From the stack trace it appears to be coming from the Runtime. The error occurs even when nothing is happening in our application

We seem to be able to somewhat reliably reproduce this in a function that is deleting layers from our map. The layers contain MessageLayers, but it's not determined if that is the reason the crash is happening:
Exception thrown: read access violation.

I'm running into the following randomly:
System.AccessViolationException was unhandled Message: An unhandled exception of type 'System.AccessViolationException' occurred in WindowsBase.dll Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
A little background:
- I'm running Runtime v100.0
- The app is written using MVVM and Prism IoC
- There's a View (TwoDView) which has a MapView
- TwoDView has a ViewModel (TwoDViewModel) which navigates -- uses RequestNavigate(...) -- to a view (ThreeDView) which has SceneView
- ThreeDViewModel responds to the navigation and applies the camera (calling a controller, created to manage the SceneView using a WeakReference<>) passed via navigation parameters
- The controller calls SetViewpointCameraAsync
There is also a back button in ThreeDView to allow going back to TwoDView for selecting another 3D area for inspection. It seems multiple calls to SetViewpointCameraAsync is causing my issue...if I use SetViewpointCamera...no issue. Any ideas??
