Trash section is disappeared

Hello,
our trash section form WordPress is disappeared. Check this Image
But we have option “Trash”. Check this Image
And if we click on “Trash” it says “1 page moved to the Trash.”, but still no trash section. Check this Image
And if we press on undo we get error message. Check this Image
Tryed to add
define('EMPTY_TRASH_DAYS', 7);
to wp-config.php file, but nothing changed.
Also tryed to add

function wpb_remove_schedule_delete() {
    remove_action( 'wp_scheduled_delete', 'wp_scheduled_delete' );
}
add_action( 'init', 'wpb_remove_schedule_delete' );

to theme’s functions.php file but still nothing. Any ideas how to fix it?
By the way, WP Version 5.2.1
