Exception thrown (...): An invalid handle was specified. #262

When asking the user to authenticate, I'm running this code every second until succesful authentication:

                try
                {
                    appKey  = await client.RegisterAsync(hueSettings.AppName, hueSettings.DeviceName);
                }
                catch(LinkButtonNotPressedException e)
                {
                    Debug.LogError($"button was not pressed yet.. {e.Message}");
                }

In the editor, this gives a normal exception from my Debug.Log statement. Compiled to UWP however the app crashes with the message: Exception thrown at 0xE3C03498 in HL2HUE.exe: 0xC0000008: An invalid handle was specified.

What could be the reason for this?

Visual Studio is supposed to "pause" when any exception is thrown. That's why the app stopped when the button was not pressed yet. When running on HL2 without VS attached everything works fine.. I'm not so used to using exceptions in this way I guess.
