My Xplane 11 has crashed/stopped working after the dialog box of the update appeared. Here is a copy of the log file.
Were you able to complete the update? The log shows you are running an old version of X-Plane (11.05). I would recommend grabbing a new copy of the installer from here and trying to update to 11.11 to see if that "just fixes it".
