UWP/XAML WebView on HoloLens 2

Hey, I'm trying to get a simple WebView to work on HoloLens2 using the XAML WebView. My simple setup works fine when I build for desktop UWP (set to XAML of course), however it throws an exception as soon as I instantiate a new WebView on HoloLens. So the following code already fails in an otherwise empty project, on HoloLens2 (ARM64), while it works fine on desktop (x64): using System; using System.Collections; using System.Collections.Generic; using UnityEngine; #if !UNITY_EDITOR && UNITY_WSA using Windows.UI.Xaml; using Windows.UI.Xaml.Controls; using Windows.UI.Xaml.Markup; #endif public class Test : MonoBehaviour { private void NavigateToUri(Uri uri) { #if !UNITY_EDITOR && UNITY_WSA WebView webView = new WebView(); #endif } private void TestNavigation() { UnityEngine.WSA.Application.InvokeOnUIThread(() => { this.NavigateToUri(new Uri("http://google.com")); }, true); } private void Start() { TestNavigation(); } } The exception is sadly not very helpful: Exception: Exception of type 'System.Exception' was thrown. at Windows.UI.Xaml.Controls.WebView..ctor () [0x00000] in <00000000000000000000000000000000>:0 at Test.NavigateToUri (System.Uri uri) [0x00000] in <00000000000000000000000000000000>:0 at Test.b__1_0 () [0x00000] in <00000000000000000000000000000000>:0 at UnityEngine.WSA.AppCallbackItem.Invoke () [0x00000] in <00000000000000000000000000000000>:0 My guess is, that it has something to do with the difference in the XAML setup on HoloLens, but as I'm not experienced with that, I'd appreciate any pointers :) Unity version: 2020.3.29f1 VS version: 2022 17.2.6 Thank you!
