Reproduce the Windows command shown in the issue and start at Ui.DrawUiAsync and WaybackDownloader.DefaultCommand.ExecuteAsync, where the logged Spectre.Console exception occurs. Trace why the original exception is unavailable during graceful shutdown; done means the command shuts down without a secondary NullReferenceException and exposes the underlying failure.
