Rendering error in VR using ArcGIS SDK

Hello developers,
When I used VR in UE5.1 with ArcGIS SDK for unreal engine 1.2 to view the mesh loaded from splk files, this render error happened (with a new empty VR template project).

You can see the empty spaces in the base map. When I move my VR headset the empty spaces change to different locations. The PC template working great but not in VR.
Do I need to set something in the project setting for VR?
Thank you!
