The error is related to the release the mediaplayer resources in https://github.com/oppia/oppia-android/blob/c5de68bdf29f2ac965bc02e266c188a2c3f07962/domain/src/main/java/org/oppia/android/domain/audio/AudioPlayerController.kt#L254. The error is thrown if the release is attempting to happen before the media player is initialized, but could also happen if, say, the player was released then a duplicate release request was sent, e.g if the user clicked stop twice or the device freezes.

I am not sure if it is caused by recent changes in https://github.com/oppia/oppia-android/pull/5179, or if this is an existing edge case(Since we're only now forwarding more exceptions to Crashlytics).
