I have a SceneView from a mobile scene package in a swiftUI app. When I add operational layers and rotate the device to landscape then back to portrait, I am consistently getting a crash with the following message:
I have updated to 200.2 but still the error persists. I also get this error occasionally when entering background mode from the sceneView. Once again if I remove operational layers or select another tab in the navigationSplitView then there is no error.
This error only appears if I have an operational layer added.

GeographyView()
