Screenshots are solid black with UE5.1.1, Unreal Engine 5 Integration 54.0

Hi,

I'm having a problem where screenshots I take of UE5 games on my Quest are solid black.

- I can repro it on a blank UE5 project by following the Quest / UE5 getting started guide at Creating Your First Meta Quest VR App in Unreal Engine: Unreal | Oculus Developers 

- Using Unreal 5.1.1 from the Epic Games Store

- Using the MetaXR plugin from Downloads - Unreal Engine 5 Integration (oculus.com) v54

- Quest 2 OS version is 54.0.0.155.344.482042629

Screenshots of UE4 builds of our game don't have this issue.

Thanks for any suggestions.
