Control not returning to main workflow after calling launch interactive workflow

@Pankaj.Patil and @Rammohan91 Main problem is serialization as datatable is not serializable and launch interactive workflow creates a separate bot process, hence it’s not being passed from one process to another. I have found the problem but not the solution. Perhaps this link will explain my problem
