See the inner exception for more information. ---> System.Exception: Information for developers (use Text Visualizer to read this):
This exception was thrown because the generator for control 'SimpleDnsCrypt.Controls.LoggingListView Items.Count:2814' with name '(unnamed)' has received sequence of CollectionChanged events that do not agree with the current state of the Items collection. The following differences were detected:
