Re-open same Custom Action after successful run of Custom Action

I have a Custom Action that creates a Task, and after successful run of that task- I want it to re-open so that the user can create another task using the same Custom Action.

Below is the code I have running on "Success". (Open URL is selected)

{If(RunAgain =TRUE,GetCustomActionUrl('My Custom Action'),GetCustomActionUrl('Do nothing'))}

**"My Custom Action" being the current Custom Action that it's running on

**"Do Nothing" Custom Action is a Custom Action that does literally nothing.

**RunAgain is a toggle. Have tried drop-downs too

However, when I run the Custom Action I am receiving an error that states: "The custom action can’t run as it is causing loops". I've also attempted to create a duplicate "My Custom Action" and have it be opened upon successful run; while it does open the duplicated Custom Action, I am receiving the same "Loops" error when trying to run the second one and open the initial Custom Action on "Success". 

Please help!!
