This error is a technical compatibility issue between the English Noun Frequency plugin and the latest versions of Python (the language Calibre runs on).

Here's what's happening:

Why does it occur?
The error AttributeError: 'ENFHTMLStripper' object has no attribute 'scripting' is due to the plugin developer inheriting functions from a Python standard library (html.parser) that changed in recent versions.

Specifically, the plugin tries to clean the book's HTML code to extract the words, but it can't find an internal parameter called 'scripting' that newer versions of Python expect. It's a "clash" between the plugin's older code and Calibre's newer code.
