Managed System Dialog crash with System.UnauthorizedAccessException, again

[fnajera-rac-de]

The bug #4171 is not completely fixed by #4181.

It is possible to have an IsReady drive for which you do not have access. In that context, operations like VolumeLabel will fail and the process crashes.

Avalonia/src/Windows/Avalonia.Win32/WindowsMountedVolumeInfoListener.cs

Lines 35 to 56 in cc2ddce

	var mountVolInfos = allDrives
	.Where(p =>
	{
	try
	{
	var ret = p.IsReady;
	return ret;
	}
	catch (Exception e)
	{
	Logger.TryGet(LogEventLevel.Warning, LogArea.Control)?.Log(this, $"Error in Windows drive enumeration: {e.Message}");
	}
	return false;
	})
	.Select(p => new MountedVolumeInfo()
	{
	VolumeLabel = string.IsNullOrEmpty(p.VolumeLabel.Trim()) ? p.RootDirectory.FullName
	: $"{p.VolumeLabel} ({p.Name})",
	VolumePath = p.RootDirectory.FullName,
	VolumeSizeBytes = (ulong)p.TotalSize
	})
	.ToArray();

See the .Dump() from LINQPad for such a drive:

To reproduce I guess you need to have a network share that you control and map, and for which you can revoke permission for your user.

Tested with 0.10.15
