Error starting the Jupyter notebook on Windows

Question

When I write jupyter notebook on my on command prompt, I get an error on cmd while running jupyter. I don't understand why this is happening again and again. Therefore, it blocks to open jupyter editor in the browser. I have added all environment variables as usual, but it's not working yet. Could you please help to solve this? Any kinds of suggestions are welcome.
