Fatal error when pressing ‘edit page’

On one specific page, I get a fatal error when loading the page with this plugin. When I disable the plugin, I am able to access the ‘edit page’ for that page fine.

The page of concern is the ‘about the garden’ page on the website.

( ! ) Fatal error: Uncaught Error: Call to a member function item() on null in /Users/lewis/Local Sites/cascades-gardens/app/public/wp-content/plugins/block-options/includes/class-editorskit-block-typography-manager.php on line 161
