Worked great, now use of the plugin block causes editor unresponsiveness

When I first added the plugin, I would have rated it high as it did the job I needed: adding a non-menu menu as a block with Gutenberg. It worked perfectly fine with my main theme & blocks builder: Kadence Pro.

I haven’t had need to change any of the places where I’m using the blocks till now – and frankly, there are major issues with compatibility and the blocks cause the WP editor to be unresponsive. (Though the front end continues to display fine.) After much back and forth, this plugin has a major conflict with Kadence theme & blocks – and it appears that the plugin’s developers have abandoned it, or changed directions that no longer align with Kadence. Sounds like it still works for some, and it still works on my site’s front end. But the plugin is unusable on the backend now with Kadence and would not recommend the combo.
