"Help-->Find Action-->Randomly selected action" by mistake

Question

My problem started when I was looking for the search function to find code in one of my Classes and dumb as I was I went to the tab many "Help-->Find action" and relized this was not the search function I was looking for.

Instead of just typing in "Ctrl + F" I pressed some random button in this "Find Action" function, pressed enter and Android Studio started doing something in the background. I first thought it was just Gradle which was syncing in the background but Android Studio restructured my whole project it seems and asked for a restart afterwards.

Now I can't run my Project or the "Application" tab that I normally have when I work on the left side is gone. How can I get my project back?

This is my what my "Edit Run/Debug Configurations"

Here is the project tab which I can't toggle to App any more

Answer 1

Check the run configuration if it has selected the "app":

Answer 2

Don’t worry, go to file menu and sync with grade files
