[ORD 10.09 C#] example AlignmentEdit Null Exception

I'm trying to develop my own Alignment Import MDL addin.

I get a null exception, I've tried running the OpenRoadsDesignerCONNECTSDK example for ComplexAlignmentCreator

and get the same null exception in this line, AlignmentEdit al = AlignmentEdit.CreateByLinearElement(con, complexAlign, true);

Is there two points that this will work for?

Can anyone confirm if they also get the same behavior? ORD CE 2021 Release 1
