App crash at startup

[LaurentInSeattle]

Hi there,

My little test app that I published yesterday and was working ok now silently crashes at startup.
I have been able to recover the trace below in the event log.

Any idea about what's going on ?
Thanks!

This is on Windows 10 fully patched and Visual Studio 22 latest 17.10.3 and the latest official Avalonia nugets 11.0.11

Application: _.Desktop.exe CoreCLR Version: 8.0.624.26715 .NET Version: 8.0.6 Description: The process was terminated due to an unhandled exception.
Exception Info: System.InvalidOperationException: Cannot perform requested operation because the Dispatcher shut down
at Avalonia.Threading.Dispatcher.PushFrame(DispatcherFrame frame) at Avalonia.Threading.Dispatcher.MainLoop(CancellationToken cancellationToken)
at Avalonia.Controls.ApplicationLifetimes.ClassicDesktopStyleApplicationLifetime.Start(String[] args)
at Avalonia.ClassicDesktopStyleApplicationLifetimeExtensions.StartWithClassicDesktopLifetime(AppBuilder builder, String[] args, Action`1 lifetimeBuilder)
at .Desktop.Program.Main(String[] args) in C:\Users*\source\repos*_.Desktop\Program.cs:line 10

Does it consistently reproduce?

If so, you may be able to subscribe to Dispatcher.ShutdownStarted to see if your app is getting shutdown in the middle of its startup sequence somehow. Then check the call stack and maybe there will be some clue as to what initiated.

Relevant code:

Avalonia/src/Avalonia.Base/Threading/Dispatcher.MainLoop.cs

Lines 35 to 43 in b1e96ad

	public void PushFrame(DispatcherFrame frame)
	{
	VerifyAccess();
	if (_controlledImpl == null)
	throw new PlatformNotSupportedException();
	_ = frame ?? throw new ArgumentNullException(nameof(frame));
	if(_hasShutdownFinished) // Dispatcher thread - no lock needed for read
	throw new InvalidOperationException("Cannot perform requested operation because the Dispatcher shut down");
