Hello @Praharsha_kanaparthi ,
May I Know What are you trying to Click using the Click Activity?
i think you need to fine tune the selector so that the click activity works fine
I guess you are trying to click (ok),in that case you can use Delay activity or Delay it using (Delay after) option in properties panel.
Try deleting send hotkey activity as it is doing the same Task as click activity.
