Research direction
Start by inspecting Wpf.Ui.Controls.SnackbarPresenter.OnUnloaded() and the cancellation-token lifecycle involved in the reported System.ObjectDisposedException. Investigate the idle unload path on Windows 10 with .NET 6 and WPF-UI 3.0.0-preview.13; done means the presenter can unload without crashing when the cancellation token source has already been disposed.
