Testimonials plugin does not appear to be working since the latest update.

1. Shortcode shows in the widget
2. No Testimonials link in the admin dashboard sidebar or any way to add a Testimonial
3. Testimonial Posts have disappeared (though they are in the database on the server) along with any kind of Post besides Staff.

WP 6.4.2 PHP 8.2 UUA Theme 1.3.3

The shortcode also seems to be appearing on the demo: https://demo.uuatheme.org/

Thanks for any help you can offer.
