How to troubleshoot crash on Android?

Hello, Ionic app compiled and deployed to google play store. It works fine on all Android devices I have, but it crashes on many devices in a wild west. App crashes on a startup allegedly, when initializing Ionic’s Secure Storage plugin. All what I get in google play console is a limited stack trace:
android.content.ActivityNotFoundException:

Any advice?
