Anyone have a resolution for this error message:

• agf.WorkTrigger: execution of AfterInsert caused by: System.NullPointerException: Attempt to de-reference a null object (agf)

This occurred after creating a new page layout and a new record type then trying to create a new work item. I have repeated this process 3 times with the same result and am unable to create new usable record types in my org (using Lightning). Thank you very much for any assistance!
