I have a WinForms based C# (.NET Framework 4.7.2) project that uses Microsoft.AppCenter 4.4.0 (AppCenter.Analytics and AppCenter.Crashes).

When I call AppCenter.Start on Windows 11 (retail), the app hangs and the call never returns:

Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);

AppCenter.Start(ourAppSecretGuid, typeof(Analytics), typeof(Crashes));

Interestingly, this doesn't happen in a debug build if I'm attached to the remote debugger. The call returns (seemingly) normally.

I know that the Visual Studio debugger has some impact on how exceptions/crashes are handled in the program under test, and I suspect that is somehow interacting with the AppCenter crash-interception logic... but I still don't know specifically why this is happening or what to do about it.

EDIT

Here's the stack trace:

I'm seeing this in Win 11 running in a Virtual Box VM. I'm setting up a physical Win 11 box to test against.
