ERR_FILE_NOT_FOUND

[hanwuli]

Why starting jupyter notebook in command line every time it can open a specific file path that's file:///C:/Users/myaccountname/AppData/Roaming/jupyter/runtime/jpserver-40780-open.html here?
Then it will show the error of file not found as shown in the screenshot below.

In fact, this file doesn't exist in the path.
It's said to be an issue with Python installation and I install it from Microsoft Store. Does it really need to uninstall the current one and then download and install it again from the official website to solve this problem?
I want to know the reason behin this.

You can find our official documentation for installing Jupyter Notebook here: https://docs.jupyter.org/en/latest/install/notebook-classic.html

If you're unable to install using Anaconda or pip, could you please provide info about the Notebook version and the Python version you're using, along with your Windows version? Thanks!

I have read the above documents but they aren't involved in my problem. Maybe I didn't express clearly before. What I encountered is the same as the follows metioned:https://github.com/jupyter/notebook/issues/5996 I want to know if there are other better ways to solve it rather than uninstalling and reinstalling Python. And Why can this happen?

Thank you for your reply @hanwuli! This is a duplicate of the currently open server issue, jupyter-server/jupyter_server#435 so I will close it in favor of that one. Please feel free to follow up on the issue in that thread.
