Error in generating sphinx

[mianasbat]

Hi,
Thanks for the helpful youtube video.
I tried the tutorial but I got an error in generating output.
I think the sphinx-quickstart also changed the script a bit.
I got the following output

Here is my sphinx version etc.

Any idea why am I getting the error.
Can you try generating the docs using your repo and see if this version of sphinx still works for you.
Many thanks
