I have seen this on my player base on a Samsung S22 Ultra running Android 14.

Here is the source code here where the bug occurs: https://github.com/bluefireteam/audioplayers/blob/main/packages/audioplayers_android/android/src/main/kotlin/xyz/luan/audioplayers/player/MediaPlayerPlayer.kt#L41

mediaPlayer.playbackParams = mediaPlayer.playbackParams.setSpeed(rate)

Here is the Android source code for getPlaybackParams():

/**
--
  | * Gets the playback params, containing the current playback rate.
  | *
  | * @return the playback params.
  | * @throws IllegalStateException if the internal player engine has not been
  | * initialized.
  | */
  | @NonNull
  | public native PlaybackParams getPlaybackParams();

You can see how it says that it throws a IllegalStateException if the Internal player engine is not initialized.
