HarmonyOS audioCapturer release失败会如何

audioCapturer release失败会如何，不论release 的结果是成功或者失败，重新赋值会对系统造成影响吗？如下面的代码：

//释放资源
(audioCapturer as audio.AudioCapturer).release((err: BusinessError) => {
  if (err) {
    console.error('Capturer release failed.');
  } else {
    console.info('Capturer release success.');
  }
});
audioCapturer = null
