Issues running the Unreal Engine 5.3 Spatial Anchors sample on Meta Quest 3 - AndroidFileClient

[Aleistor222]

I am trying to build the Spatial Anchors sample project on Unreal Engine 5.3 (Oculus-VR Source) but receiving an error message related to the AndroidFileClient. The Passthrough and Scene samples have built to my Meta Quest 3 without failure so I'm assuming it has something to do with the Spatial Anchors project needing to save anchors to the headset file system.

I am very new to Unreal so I apologize if this is a stupid question and I'm missing something obvious. I've been through the Meta documentation on this sample and have searched the web and can't find anything related or anyone else that has encountered this issue. I did not try this sample project on any previous versions of Unreal so I'm unsure if this is an issue with the new Oculus-VR build of UE5.3.

Any help would be greatly appreciated!

This is the relevant section of the output log when trying to build:

I would disable Android File Server in project settings, just build the .apk and don't deploy it to the device.
Then i would install the apk separatedly using adb install "path_to_your_apk"

I was able to fix this by disabling windows defender for my project directory
