Sample APK Does Not Open on Headset

Hello! I've been unable to get any Unity app to open on the headset. I can't get the APK from Qualcomm to open (in the SDK folder you shared last week); and I can't get a new Unity project with the imported SDK to open either.When I open either app, it just displays a blank screen. And about 2/3rds of the time, the app (on the "host device", i.e. the Motorola phone that the headset is hooked up to) crashes with the following stack trace:

From the logs it looks like Unity tries to open, but ARFoundation fails to initialize the XR subsystem:

I Unity   : [XR] [516836617392] [13:34:32.847][Error  ] xrDestroySession: XR_ERROR_HANDLE_INVALID
W Unity   : No active UnityEngine.XR.ARSubsystems.XRSessionSubsystem is available. Please ensure that a valid loader configuration exists in the XR project settings.
W Unity   : UnityEngine.XR.ARFoundation.SubsystemLifecycleManager`3:GetActiveSubsystemInstance()

I should note that all of this is from the example APK created by Qualcomm themselves. Their documentation states that you should troubleshoot your own application not working by trying out their sample APK. But their sample APK doesn't even work. I've tried everything else I can come up with: clean restart, updating the host device OS version, perusing their docs for anything I've missed. Nothing has worked.

Does anyone have tips on how to fix this? Thank you for your time and help!

Copying from a ticket - as these are the steps we're going to tell you to do to help us narrow down where the error could be.

Hi Ketaki,

So let's eliminate a few things - first make sure that your glasses are connected correctly.

https://support.spaces.qualcomm.com/support/discussions/topics/72000779370

Note the comment about the USB-C cable.

Verify that you are running a recent version of Spaces Services (0.7.0 is a good one) - long press the Snapdragon Services icon and bring up App Info - the version number is at the bottom

Reboot your phone, plug in the glasses and let them boot up.

Run the Unity samples that come with the Snapdragon Services - they pretty much always work. Always exit the sample using the Quit button to gracefully shut things down.

If that fails, then make sure the Spaces Services is NOT running (Press Spaces Services icon, and force stop if it's running) unplug/replug the glasses, let them boot and try again.

If this fails 3x in a row without rebooting the phone, then we've got an issue. It's not unusual to get a fail to launch a time or two.

If the samples work then you should be able to create Spaces apps yourself. If they fail then there's some issue and we'll assist in getting you up and running.

Please send me the phone's serial number (Settings->search for "serial" - it's a 10 character string)
