Fragment issue?

I have what I believe is a relatively simple program, 381612. I have no idea why Google won’t accept it but below is the error message. Is there something that I did wrong or that I can do to correct this?

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.myvancomycincalculator.app/com.myvancomycincalculator.app.MainActivity}: androidx.fragment.app.Fragment$InstantiationException: Unable to instantiate fragment com.swmansion.rnscreens.ScreenFragment: calling Fragment constructor caused an exception
