Android Studio generated an APK crash when launching the application on the same phone. What's wrong?

Question

First of all, I am completely new to all of this.

I am using Android 2.1. When I run the code for the application on my phone, everything works fine. However, when I create a signed APK and install the application on my phone (after deleting files from the software runs), it somehow starts to be massively postponed, a black screen appears, the user interface stops working, memory and CPU usage and the application and the phone stops working together.

When I create an APK, I install it as a debug version. I tried both a signed APK and a non-signed APK. In both cases the same thing happens.

In addition, the application suddenly takes up 12 megabytes, while the application has only 6 actions and no images except the launch icon.

Can someone help me? Thanks in advance.
