Error message when clicking columns when using "Enhance Main Window" add on

I keep getting this error any time I click on a column:

Wondering if this is a known issue? Thanks!

Troubleshooting

If the error is due to an addon, you can report it to the author.

I’m not sure that Arthur has kept up development on this add-on. so it might be end-of-life. Contacting him is the best next step.

Adding a link to its GitHub repo – which is missing from the add-on page: GitHub - Arthur-Milchior/anki-enhance-main-window: Adds a lot of features to the main window, and to configure them

Gotcha, thanks! I posted an open issue as well.
