errors in jupyter kernel?

Question

I am new to the use of Jupiter and have set up a kernel, but an error is preventing anything happening. Any help would be appreciated. The text below is the error coming once I click on kernel error.

Traceback (most recent call last):

I had a similar issue. I have tried to reinstall the pywin32 package with pip but it did not work either

pip install pywin32

What solved my issue was to install it with conda

conda install pywin32

The version of the package is the same (227), but conda does something that pip does not.
