Persistance must be configured error

Nothing is invoked

there is an invoke:

it is using Wait/Resume in XAMLs others as flagged as Main Entry Point. So it is causing this issue

2019.10 - Invoke Workflow error

I think you cannot use the Wait for Form Task and Resume activity in an invoked workflow. These persistence activities only work from the Main.xaml (or any workflow in you project that is marked as the main one).
