Facing Error with "Build Your First Automation Process" -" Index was out of range. Must be non-negative and less than the size of the collection"

I am facing this error while I was completing the following the video tutorial for - Get Started with RPA Development - Build Your First Automation Process

Source - Save Last Task Mail Attachments

Message - Index was out of range. Must be non-negative and less than the size of the collection

Parameter name : index

Mine is the same. I’m going to try to work through the next video and see if it says anything about it.

Thanks Brother.
