Cannot use Scene API/MRUK with Quest Link on UE 5.3.2

On the latest version of the Oculus Source build (UE 5.3.2, v62), I can't execute anything relating to the Scene API while testing in editor over Quest Link (using a Quest 3). It auto-fails without any warning, aside from the following error.

LogMRUK: Error: Launching capture flow failed!

 Anyone have any idea what's this caused by? It works fine in builds, but that's very annoying to have to build every time I want to test.
