Family Manager Type Creation Fail

I specifically want to handle the case where a user has deleted the last type from a family and then I want to create a new type.

Please refer to: http://help.autodesk.com/view/RVT/2019/ENU/?guid=Revit_API_Revit_API_Developers_Guide_Revit_Geometric_Elements_Family_Documents_Managing_family_types_and_parameters_html

The code fails here:

			try: 
				famDoc.FamilyManager.NewType(xTypeName)
				loadOpts = FamilyOption()
				oFamily = famDoc.LoadFamily(doc, loadOpts) 
			except:
				pass

The error message is below, and note the script stops without passing values to the other nodes:

Even though the family type is now in the project:

Any help is greatly appreciated
