{"type": "OPERATION_TIMEOUT"} error on startAudio in iOS Safari

I am experiencing an issue with the Zoom Video Web SDK sample app code on iOS Safari. When attempting to start audio using the startAudio function with no any parameters, the operation gets stuck and eventually throws an error with the message: {"type": "OPERATION_TIMEOUT"}. This issue occurs intermittently and affects the ability to start audio reliably.

Browser Console Error

Which Web Video SDK version?

Video SDK Code Snippets

const onMicrophoneClick = useCallback(async () => {
    if (isStartedAudio) {
      if (isMuted) {
        await mediaStream?.unmuteAudio();
      } else {
        await mediaStream?.muteAudio();
    } else {
      try {
        await mediaStream?.startAudio();
      } catch (e: any) {
        if (e.type === 'INSUFFICIENT_PRIVILEGES' && e.reason === 'USER_FORBIDDEN_MICROPHONE') {
       message.error(e?.reason || JSON.stringify(e));
  }, [mediaStream, isStartedAudio, isMuted]);
