Please let me know a workaround.

Somehow python.exewas failing and because of that internal function like VideoFileClipwas giving error in jupyter-notebook.
不知何故python.exe失败了，因为内部函数就像VideoFileClip在jupyter-notebook.
Then I closed everything and restarted back and voila, error was gone and it's working fine now.
然后我关闭了所有东西并重新启动，瞧，错误消失了，现在工作正常。

I solved the issue by running the following commands after reading the video.
我在阅读视频后通过运行以下命令解决了这个问题。
video_clip.reader.close()
video_clip.audio.reader.close_proc()
See https://github.com/Zulko/moviepy/issues/73and https://github.com/Zulko/moviepy/issues/164.
请参阅https://github.com/Zulko/moviepy/issues/73和https://github.com/Zulko/moviepy/issues/164。

What worked for me, was closing Explorer, as gene tsai suggested. Worked instantly. I was using os.listdir(dirpath) when I got the error.
正如基因蔡所建议的那样，对我有用的是关闭资源管理器。立即工作。出现错误时，我正在使用 os.listdir(dirpath) 。

On windows 10, I did not able to call VideoFileClip() more than 5 times. clip.close()solved my issue, you need to close clips after you don't need:
在 Windows 10 上，我无法调用 VideoFileClip() 超过 5 次。clip.close()解决了我的问题，您需要在不需要后关闭剪辑：
clip = VideoFileClip("asd.mp4")
...
clip.close()
