RuntimeError: An attempt has been made to start a new process before the current process has finished its bootstrapping phase.

I'm having the following issue, any help would be appreciated. I'm using Python 3.10.2.

chrome = Chrome()
youtube = Youtube(
    browser=chrome
)

result = youtube.upload(video_path=video_path,
               title=title,
               description=description,
               tags=tags,
               made_for_kids=made_for_kids,
               visibility=visibility,
               # thumbnail_images_path=thumbnail_images_path,
               timeout=timeout)`

Here is the stack trace:

        This probably means that you are not using fork to start your
        child processes and you have forgotten to use the proper idiom
        in the main module:

            if __name__ == '__main__':
                freeze_support()
                ...

        The "freeze_support()" line can be omitted if the program
        is not going to be frozen to produce an executable.

Put all your code under:

if __name__ == '__main__':

It will resolve the issue
