Main method not found in the file after debugging!

As directed , after completing Setup-2 , When I tried to debug the file.
Error appears as indicated in the picture ( pic 2).
I’ve checked there is a main class defined in the class ( see in the first pic )but don’t know why is it appearing again and again after debugging the code.

Hey, can you please refer to this FAQ,
I think you’re in the wrong directory.
Also, if the issue still exists, tag me.

Are you using the break at return statement at 47/48 and then the beaker on the left pane?
