NavigationLink not working when used with picker

I have a form container with a Navigation Stack at the top level. In a section I have a Navigation link followed by Picker(s) . On its own the navigation link works correctly but when a HStack with Text and Picker is added the navlink breaks . When the link is selected the picker is presented. It seems others have had this issue which is usually solved by adding the NavigationStack , which is already at the top level. Any other suggestions are greatly appreciated
