Create pagination in the items list of specified custom taxonomy term

I’ve created list of custom taxonomy term and have problem with pagination.

Custom post type “gallery” has his own custom taxonomy “gallery_category”. The next loop lists all items of chosen Gallery category:

I’m using WP PageNavi plugin to create pagination and I’m facing the problem with “get_queried_object()” function.

It takes term name from the link: https://domain.ltd/gallery/categories/term-slug.

When I click on next page, link changes to: ../gallery/categories/term-slug/page/2. Because link slug has been changed I’m getting an error.

Maybe you have any ideas how could i solve this problem? Thanks.
