App update on play store

I had an initial issues with an app I was doing which has been resolved.
But the issue is, in the process of troubleshooting the crisis, I uninstalled the SAB builder and removed all it’s folders using CCleaner. Now I saw a mistake in the first app which I’d love to correct by doing an update. What are the things I should have in mind? Is it still possible to update the app?

Thanks once again for your anticipated assistant and your past help.
