Getting error here was an attempt to perform an action at a point, which is beyond the screen.

Hi Jainsoumya,

Thank you for the logs files. 

In the failing log I see that PowerPoint has a 'Recover Unsaved File' message. This is most likely altering the interface and the position where the cursor needs to be to change the size of the slide. I would work on making sure that error does not come up, as you will most likely need to create a new action for the altered interface with that message.

Let's get that error out of the way and let us know if that improves your test.
