PivotGrid: Error when dragging pivot fields

Good day,
I am having an issue with the Pivot grid when trying to drag a field into any of the pivot field boxes (row, column, and Value fields - Filter field works for some reason), in which an application exception appears at "Application.Run(New Form1())" in the Program.cs, so that doesn't actually give any information. The stack trace gives:

Do you have any ideas as to what may be causing this?
Thank you!

Hi Travis, 

We have checked the mentioned issue – “Exception was thrown while drag and drop the fields into the Rows, Columns and Values section of schema designer” in your version 16.2.0.41. But we are unable to reproduce the reported issue in our side. We could not face any exception while drag and drop the fields within the schema designer. 

Refer the attached videos from the following location: 

Please find our working sample from the following location: 

Could you please share your working sample or modify the attached sample in order to reproduce the reported issue, it could be helpful to provide the solution at the earliest.

I'm actually having the same issue even with the samples included with essential studio, do it is not unique to my code.
