App crashes when downloaded from Google Play

I've just built and deployed an app to Google Play. It worked well when I was running it through Android Studio but now it crashes when I download it from Google Play. Because this is my first time, I don't even know how to view the crash report/stacktrace of the app that was downloaded from Google Play. I appreciate any and all help.

UPDATE

So I got the stacktrace for the APK. It tells me that my TopImageFragment.java class cannot create my MemeViewModel.java class. I have no clue why its giving this error. Everything works fine as it is. It seems that proguard is indeed phasing out an important class:
