Уведомление PlayerNotificationManager начинает мерцать при добавлении прослушивателя в Activity ⇐ Android

[Anonymous]

Я пытаюсь создать проигрыватель фоновой музыки, используя библиотеку media3. Медиаплеер работает нормально, но уведомления начинают мерцать всякий раз, когда я добавляю прослушиватель в основное действие для обновлений на переднем плане в действии.
Строка, вызывающая проблему
val controllerFuture = MediaController.Builder(this@MainActivity, sessionToken).buildAsync()

Иногда уведомление формируется без кнопок поиска, но обновляется, когда я нажимаю любую кнопку в уведомлении. После удаления вышеуказанной строки уведомление работает без проблем.

putParcelableArrayListExtra("playList", playlist)
putExtra("startIndex", startIndex)
action = "ACTION_PLAY_NEW"
}
requireContext().startForegroundService(intent)
