Exception when opening explorer

[William Besnard]

That's a pretty specific issue, but I thought I'd report it anyway :)

When opening a folder in explorer on Windows 10 through a button, few Exceptions are raised:

here's the piece of code that create the exception:

#if UNITY_EDITOR

    [BoxGroup("Save Directory"), MultiLineProperty]
    public string FullSaveDirectory { get { return Application.persistentDataPath + SaveDirectory; } }

    [ShowInInspector,BoxGroup("Save Directory")]
    public bool IsDirectoryCreated { get { return Directory.Exists(FullSaveDirectory); } }

    [BoxGroup("Save Directory"), Button(ButtonSizes.Medium)]
    public void OpenSaveDirectory()
    {
        if (IsDirectoryCreated)
            Process.Start(@Application.persistentDataPath + SaveDirectory);
        else
        {
            Process.Start(@Application.persistentDataPath);
        }
    }
#endif

This could be hard to do anything about, as it seems to be caused by the GUI drawing chain ending when you start the process for some reason. Evt because Unity loses focus?

You should be able to get rid of the exception by using UnityEditor.EditorApplication.delayCall though:

[BoxGroup("Save Directory"), Button(ButtonSizes.Medium)]
public void OpenSaveDirectory()
{
    if (IsDirectoryCreated)
    {
        UnityEditor.EditorApplication.delayCall += Process.Start(@Application.persistentDataPath + SaveDirectory);
    }
    else
    {
        UnityEditor.EditorApplication.delayCall += Process.Start(@Application.persistentDataPath);
    }
}

I get this same error upon double-clicking a Sprite object inside of an OdinMenuEditorWindow. It appears to be the same issue because when I do double-click this Sprite object, it opens the png file in a new window in the Windows Photos app. In this particular instance, I can't really use the workaround you mention since I don't control any of the code that opens the file.

On the other hand, the error doesn't really seem to break anything, so I'm not exactly worried about it. I just came across this ticket when googling the error.
