Launcher.LaunchFileAsync fails to open path with space on macOS

[tompnub]

Describe the bug

When trying to open a folder whose path contains a space using Launcher.LaunchFileAsync (or the LaunchDirectoryInfoAsync extension method) on macOS, the file path is interpreted as two separate files and an error written to the debug console, while the method returns true.
This is a similar issue to #17301 on Linux, as fixed in #17682

To Reproduce

1. Create an empty C# .net8.0 Avalonia project using the Avalonia .NET MVVM App template, Avalonia 11.3.6.
2. Add a button to MainWindow.axaml and the following code to its click event:

	private void Button_OnClick(object? sender, RoutedEventArgs e)
	{
		Dispatcher.UIThread.InvokeAsync(async () =>
		{
			// replace <username> and <appfolder> with the relevant values, must be a valid folder path containing a space
			Uri folderUri = new Uri("/Users/<username>/Library/Application Support/<appfolder>");
			var storageResult = await StorageProvider.TryGetFolderFromPathAsync(folderUri);
			// check that storageResult is a valid object whose properties represent the folder
			bool result = await Launcher.LaunchFileAsync(storageResult);
			// result == true
			// Debug console:
			// The files /Users/<username>/Library/Application and /Users/<username>/Documents/<pathtomysolution>/src/<avaloniaprojectfolder>/bin/Debug/net8.0/Support/<myapp-folder> do not exist.
		});
	}

3. Set breakpoints, debug the project and press the button.

Expected behavior

The directory with a space in its path should open in Finder.

Avalonia version

11.3.6.

OS

macOS

Additional context

macOS version: Sequoia 15.6.1 (24G90)
My workaround is to run Launcher.LaunchUriAsync, which correctly opens the directory, although that has issues in Windows 10 and could lead to different results if the path is a file not a folder, etc.

Can you try with Launcher.LaunchFileInfoAsync or Launcher.LaunchDirectoryInfoAsync (since app bundle is actually a directory)?

[tompnub]

I have tried all the different variations in a different folder, i.e.

"/Users/username/Documents/_TEST/_stuff/Folder With Spaces/"
"/Users/username/Documents/_TEST/_stuff/Folder With Spaces/file name with spaces.txt"
Launcher.LaunchFileAsync with valid IStorageFolder and IStorageFile
Launcher.LaunchDirectoryInfoAsync with valid DirectoryInfo
Launcher.LaunchFileInfoAsync with valid FileInfo

I have uploaded some test code and results here:
https://pastebin.com/Fbg1TZQv

In all four cases with valid files and directories, the message "The files X, Y, Z do not exist" is written to the debug console, the method returns true, but neither Finder nor TextEdit are opened. (X, Y and Z appear to be split parts of the string treated as multiple absolute or relative paths depending on the /)

From the source it appears both the LaunchDirectoryInfoAsync and LaunchFileInfoAsync extensions call Launcher.LaunchFileAsync internally.

I am testing this in JetBrains Rider in Debug mode, I could also do an app bundle test of our app, but I'm not sure if that would change anything.
