WP Hardening / WP 5.9 – Can’t create new posts or pages with plugin activated

I just upgraded to WP 5.9 and while the front end of my website works fine I cannot create new pages or posts. I deactivated each plugin one by one and discovered it is WP Hardening causing the conflict.

This is the error message

TypeError: Cannot read properties of undefined (reading 'ref')

Other then deactivating the plugin is there a fix at all?
