When attempting to install the latest update in our O11 Version 11.0.607.0 environment errors are generated and I have to re-install the previous version.

When I extract the .oml from the .oap file and attempt to open the oml directly in Service Studio, the error generated is:

ServiceStudio.Presenter.RuntimeImplementation+FullStackException: Exception in thread Main ---> ServiceStudio.Presenter.AggregatorPresenter+prs#plwtnvxw: Error opening file 'C:\Users\mdrevyanko\Desktop\DragAndDropAndSort.oml' ---> System.NullReferenceException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object.
