[Problem/Bug]: WebView2 control in an UWP crashes the entire console on Xbox One

[Pasquiindustry]

What happened?

I'm having a very strange issue.
I'm trying to make an app that uses - and need to use - the WebView2 control.

The minimum example that triggered the issue:

• Create a new empty UWP project (.Net 9, target 10.0.26100.0, supported 10.0.19041.0 or 10.0.17763.0) or an UWP project (.NET Native)
• Add Microsoft.UI.Xaml from Nuget (v2.8.7, which depends on Microsoft.Web.WebView2 1.0.2849.39 - more on that later)
• Add the WebView2 Control. The same issue happens when the control gets added directly inside the MainPage.xaml file or inside the Loaded event in MainPage.xaml.cs. I've provided an example below.
• I've also updated manually the Package.appxmanifest, just the <Identity Name="[...]" Publisher="[...]" Version=[...]" /> tag. I also assigned a certificate I made since the "Associate App with Store" button is currently having issues on the Microsoft side. The Store is not complaining, the PC version works, I don't think there's a problem here.
• Create the package. I tried different combinations of
  • Just a Release x64 or both Release x86 and Release x64.
  • Relased as .msix, .msixbundle and .msixupload

Here's the content of the <Page> tag of MainPage.xaml

<Grid x:Name="UiLayoutRoot">
    <controls:WebView2 x:Name="UiWebView" Source="<any website>" />
</Grid>

I also tried this code without the XAML above

WebView2 UiWebView;

private async void MainPage_Loaded(object sender, Windows.UI.Xaml.RoutedEventArgs e)
{
    UiWebView = new WebView2();

    // Tried both with and without these
    UiWebView.IsHitTestVisible = false;
    UiWebView.IsTabStop = false;
    UiWebView.AllowFocusOnInteraction = false;
    UiWebView.AllowFocusWhenDisabled = false;

    this.Content = UiWebView;
    [...]
}

This app works without any issues on

• Multiple PCs on version 26100
• On an Hololens emulator on version 22621

However, it doesn't always work on Xbox

• On an Xbox One in retail mode, it crashes the entire console, not just the app. Here's what I see from a console streamed through Discord:

  • The splash screen appears
  • The WebView cursor appears (with the splash still visible and without App.Current.RequiresPointerMode = ApplicationRequiresPointerMode.WhenRequested;
    )
  • The splash screen disappears (with the cursor still visible)
  • Black screen (with the cursor still visible) of the console immediately followed by a crash of the console that restarts itself

• On an Xbox One in dev mode, the app seems to work without issues

• On one Xbox Series S in retail mode, the app crashes on startup or the Web View appears briefly with an "Out of memory" message from the WebView and the console seems to became unresponsive.

• On another Xbox Series S in retail mode, the app manages to start and work flawlessly, however it takes more than 12 seconds after the splash screen to load

• On a Xbox Series X in retail mode, the app manages to start and work flawlessly, however it takes about 6 seconds to start after the splash screen.

Without the WebView2 and with other controls (Grid, StackPanel, Button), the app works flawlessly on both PC and Xbox.

Unfortunately I don't have an Xbox myself to test in dev / retail mode (The app is on the Microsoft Store as a hidden app) and the Store is not giving me any log or dump.

Visual Studio 2022 and its components are fully updated. All the PCs and both Xbox-es are on version 10.0.26100

I also noticed that my UWP project has some outdated packages that are indicated as updated, but they aren't. I tried a manual update of these packages, but nothing changes.

• Manually installed the update Microsoft.Web.WebView2 instead of using the transitive package from 1.0.2849.39 to 1.0.3537.50
• Microsoft.Windows.SDK.BuildTools from 10.0.22621.3233 to 10.0.26100.6901 (Why it's out of date?)
• Microsoft.Windows.SDK.BuildTools.MSIX from 1.3.20250314.1 to 1.7.20250829.1

To update the Microsoft.Windows.SDK.BuildTools Microsoft.Windows.SDK.BuildTools.MSIX I changed this part of the xml of the project file with the code below, since both packages are implicit references of the SDK, which is at <TargetFramework>net9.0-windows10.0.26100.0</TargetFramework>

<ItemGroup>
  <PackageReference Include="Microsoft.UI.Xaml" Version="2.8.7" />
  <PackageReference Include="Microsoft.Web.WebView2" Version="1.0.3537.50" />
<!-- Added manually -->
  <PackageReference Include="Microsoft.Windows.SDK.BuildTools" Version="10.0.26100.6901" />
  <PackageReference Include="Microsoft.Windows.SDK.BuildTools.MSIX" Version="1.7.20250829.1" />
</ItemGroup>

Is there something I'm missing?

Hi, @Pasquiindustry!

It seems that your issue contains the word "crash". If you have not already, could you attach a crash dump as a comment?

WV2 crash dumps are located in a subfolder of the app's user data folder (UDF): <UDF>\EBWebView\Crashpad\reports\. By default, the user data folder is created in the app's folder with a name like <App Exe Name>.exe.WebView2. Refer to Crash Diagnostics for more information.

Thank you for your cooperation!
