[BUG] [UWP] ACS exception when sending video in Hololens (ARM64)

[zorderjohn]

Library name and version

Azure.Communication.Calling.WindowsClient 1.10.0

Describe the bug

I am creating an application to initiate a call to a Teams user by following the steps outlined here:
https://learn.microsoft.com/en-us/azure/communication-services/quickstarts/voice-video-calling/get-started-with-voice-video-calling-custom-teams-client?tabs=uwp&pivots=platform-windows

If deployed to PC (x64) it works for video and for audio.

If deployed to Hololens (ARM64), it only works for audio. If I send video (either using the frontal camera, or sending generated raw frames) the app crashes.

Expected behavior

The application should work to stablish a call to a Teams user, using audio and video.

Actual behavior

The application crashes if we send video in a video call. The exception is:
Unhandled exception at 0x00007FFA1EEB390C (ucrtbase.dll) in teams_uwp.exe: Fatal program exit requested.

Call stack:

Reproduction Steps

Folllow steps in https://learn.microsoft.com/en-us/azure/communication-services/quickstarts/voice-video-calling/get-started-with-voice-video-calling-custom-teams-client?tabs=uwp&pivots=platform-windows

Now modify it to add outgoing video.

Create camera stream:

_devMan = await _callClient.GetDeviceManagerAsync();
var camera = _devMan?.Cameras?.FirstOrDefault();
_cameraStream = new LocalOutgoingVideoStream(camera);

Add it to the options when starting the call:

var options = new StartTeamsCallOptions()
{
    OutgoingVideoOptions = new OutgoingVideoOptions() { Streams = new OutgoingVideoStream[] { _cameraStream } }
};

_teamsCall = await _teamsCallAgent.StartCallAsync(new MicrosoftTeamsUserCallIdentifier(cteCallee), options);
Start the video when the call is connected:

await _teamsCall.StartVideoAsync(_cameraStream);

Hi @zorderjohn, we are currently looking into this. Just to confirm, are you seeing this on HoloLens 2?
