CKAN crashing on startup

[Turbo Ben]

Hi all, I've been having trouble with CKAN since it updated about a month ago. I haven't played KSP for a while as I've not had the time, but I occasionally check CKAN to see if mods have been updated for 1.11, as I still have 1.10 installed.

The problem occurs on starting CKAN.  The program opens and starts running through startup processes. When it gets to "Updating filters..." I get an unhandled exception error message.  If I click on details, I get the following:

************** Exception Text **************
System.NullReferenceException: Object reference not set to an instance of an object.
   at System.Windows.Forms.Control.MarshaledInvoke(Control caller, Delegate method, Object[] args, Boolean synchronous)
   at System.Windows.Forms.Control.Invoke(Delegate method, Object[] args)
   at CKAN.ManageMods._UpdateModsList(Dictionary`2 old_modules)
   at System.Threading.Tasks.Task.Execute()
--- End of stack trace from previous location where exception was thrown ---
   at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()
   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)
   at CKAN.ManageMods.<UpdateModsList>d__91.MoveNext()
--- End of stack trace from previous location where exception was thrown ---
   at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()

Whether I click "continue" or "quit", the program locks solid and won't close. I need to use task manager to force it closed.

I've just tried deleting CKAN.exe and dowloading it again, but I still get the same problem.

 

Any suggestions?

This workaround should get you back in business:
