Module not specified?

Question

I have recently started learning android development, and I just built an app that changes color and text based on pushing buttons and gestures. It ran fine on my phone (Yay!), but then on my second run, an error occurred. When hitting the "run" button, an edit configurations window opened up:

I also noticed, that on the side where my project tree should be is this instead:

I don't think there is an issue in the code because it was running fine before, but I would be happy to post the code if needed.

Also

I dont know if this was the reason, but i'll include this anyway, I tried changing the name of my project, but it wouldn't work, but I changed it back. I included this in my question because that's literally the only thing I did before this error occured.

Thank you so much for helping out a fellow programmer, I really appreciate it. I have been looking at many other forums (for some hours) about this topic, but still couldn't trouble shoot this problem. It seems kind of odd that it was working first, and then it just randomly stopped working. I cant wait for your response!

Here is the dropdown for Module: As you can see, that is the only option.

Solution

Are you sure you are opening the project as android gradle project ? Try to import the program not open it
