Imported categories and taxonomies disappeared after activating plugin

Hi there!

How are you?

I’m referring the following post, since it is exactly the same only with no success in finding the solution for it.
https://wordpress.org/support/topic/plugin-category-order-and-taxonomy-terms-order-imported-categories-and-taxonomies-disappeared-after-enabling-admin-sort?replies=4

The site its not a multisite.

i ve tried deactivating the plugin, unclick “Admin Sort” and save, unfortunately nothing.

Though the posts are appeared normally in the front screen. and also back in the posts it shows which categories they are in.

But in Categories there aren’t ANY category appearing..

Please help, What should i do to get categories appeared again?

Thank you in advanced.
