Null Pointer Exception

Getting an error on clicking Run. Pls suggest.
Below is the screenshot :

@Pankit Do you have arguments set in the Main.xaml ? Also Let us know what is the version of Studio that you are using.

2020 10.2 enterprise

No arguments.

@Pankit I think it is recognised as a Bug in the Earlier versions of Studio according to the post provided below. You may need to upgrade your Studio to 2019.10.4 or Higher.

How to upgrade in Enterprise version?

@Pankit My Aplogies, I was referring to your Studio version as 2019.10.2 :sweat_smile: .

Can you also let us know if you have any workflow, Activity or State Commented in your Project ?
