Android Studio 3.1: Compiled App keeps crashing after reopening with AudioFlinger errors

I'm using Android Studio 3.1 to compile my app. It works fine on first load, but if I close the app (from the app drawer) and then re-open it, it crashes as soon as it launches, and can't ever be relaunched.

Note that this is a React Native project, and I'm not using any audio capabilities of Android in my app:

Android studio gives me these errorsin logcat.
