Invoke on UI thread with Dispatcher causes PlatformNotSupportedException in StartWithClassicDesktopLifetime

[codecat]

Describe the bug

When you try to invoke something on the UI thread before the application has started, it will throw a PlatformNotSupportedException when starting the application. The action is successfully invoked.

To Reproduce

Simply call Dispatcher.UIThread.Invoke before starting the application. Here's example code:

Dispatcher.UIThread.Invoke(() => { });
BuildAvaloniaApp().StartWithClassicDesktopLifetime(args); // PlatformNotSupportedException

Expected behavior

I would expect one of two things to happen:

• Invoke() should throw before the app has started
• StartWithClassicDesktopLifetime() should not throw a PlatformNotSupportedException in this case

Avalonia version

11.1.0-rc1

OS

Windows
