App crashed?

I do place a try...catch there.

github.com/1Remote/1Remote@bceb2928f1/Ui/View/Host/ProtocolHosts/AxMsRdpClient09Host.xaml.cs (L812-L830)

If this code is called before RDP desktop is displayed, the error will occur. Unfortunately, Microsoft does not provide an interface to detect if the RDP desktop login has displayed. I know there is an "OnLoginComplete" callback, but it has been tested and found that it does not trigger after the RDP desktop is displayed.

In order to set resolution successfully, I called SetRdpResolution times. It is normal for one of the calls to fail, so if the app doesn't crash, let's just ignore this issue.

Yes it crashed.

As far as I can say, there was logon screen active remotelly when it crashed, and after I restarted 1RM and the connection, it displayed the desktop immediatelly.
