Interesting issue!

This sounds like a common problem with YouTube Iframe API and React. Here are some potential solutions:

1. Ensure YouTube API script is loaded only once

Wrap the script loading in a useEffect hook with an empty dependency array to ensure it's loaded only once:

jsx
useEffect(() => {
  const script = document.createElement('script');
  script.src = '(link unavailable)';
  document.body.appendChild(script);
}, []);

2. Use a ref to store the player instance

Create a ref to store the YouTube player instance and reuse it:

jsx
const playerRef = useRef(null);

useEffect(() => {
  if (!playerRef.current) {
    playerRef.current = new window.YT.Player('player', {
      // your player options
    });
  }
}, []);

3. Check for YouTube API readiness

Verify the YouTube API is ready before rendering the player:

jsx
useEffect(() => {
  window.onYouTubeIframeAPIReady = () => {
    // render the player or update the player instance
  };
}, []);

4. Unmount and remount the player

Try unmounting and remounting the player when switching components:

jsx
useEffect(() => {
  return () => {
    if (playerRef.current) {
      playerRef.current.destroy();
    }
  };
}, []);

5. Use a library like react-youtube

Consider using a library like react-youtube that handles the YouTube API integration for you.

Full example

jsx
import React, { useEffect, useRef } from 'react';

declare global {
  interface Window {
    onYouTubeIframeAPIReady: () => void;
    YT: any;
  }
}

const YouTubePlayer = () => {
  const playerRef = useRef(null);

  useEffect(() => {
    const script = document.createElement('script');
    script.src = '(link unavailable)';
    document.body.appendChild(script);

    window.onYouTubeIframeAPIReady = () => {
      if (!playerRef.current) {
        playerRef.current = new window.YT.Player('player', {
          // your player options
        });
      }
    };

    return () => {
      if (playerRef.current) {
        playerRef.current.destroy();
      }
    };
  }, []);

  return (
    <div>
      <div id="player" />
    </div>
  );
};

If none of these solutions work, please provide more details:

1. Your player options and configuration
2. Any error messages or console output
3. Your React and YouTube API versions
