To automatically sort a custom post type by date in the WordPress admin, you can use the pre_get_posts action hook. Here’s a function that you can add to your theme’s functions.php file or a custom plugin:

Explanation:

• is_admin(): Ensures that the function only runs in the admin area.
• $query->is_main_query(): Ensures that we are modifying the main query, not any secondary queries.
• $query->get('post_type') === 'your_custom_post_type': This condition ensures that the sorting is applied only to the specific custom post type you want to target. Replace 'your_custom_post_type' with the actual slug of your custom post type.
• $query->set( 'orderby', 'date' ): Orders the posts by the date field.
• $query->set( 'order', 'DESC' ): Sorts the posts in descending order (most recent posts first).

This function will automatically sort the posts of the specified custom post type by date in the WordPress admin area.
