Order by date doesn't work

I use a query to get results by the distribution's movies per year and all corresponding critics to each of them too
the query

Code:

SELECT
        CONCAT('<a href="./index.php/searchid?ID_films=',
                `mt_films`.`ID_films`,
                '">',
                `mt_films`.`Title1`,
                '</a>') AS `Title`,
        `mt_films`.`ID_films` AS `ID_films`,
        `mt_films`.`distributor` AS `distributor`,
        CASE
            WHEN `mt_films`.`poster` = '-1' THEN CONCAT(`mt_films`.`ID_films`, '.jpg')
            ELSE CONCAT('000', '.jpg')
        END AS `photo`,
        `t_country`.`country` AS `country`,
        DATE_FORMAT(`mt_films`.`date_out`, '%d/%m/%Y') AS `date_out`,
        GROUP_CONCAT(DISTINCT '<a href="./index.php/people?ID_person=',
            `t_people`.`ID_person`,
            '">',
            `t_people`.`person`,
            '</a>'
            SEPARATOR ', ') AS `director`,
        CONCAT('(',
                CONVERT( COALESCE(`mt_films`.`product_year`, '') USING UTF8),
                ' ',
                COALESCE(`mt_films`.`format`, ''),
                ' ',
                CONVERT( COALESCE(`mt_films`.`duration`, '') USING UTF8),
                '\')') AS `id`
    FROM
        (((`t_country`
        JOIN (`t_people`
        JOIN (`mt_films`
        JOIN `st_peoplefilms` ON (`mt_films`.`ID_films` = `st_peoplefilms`.`ID_films`)) ON (`t_people`.`ID_person` = `st_peoplefilms`.`ID_person`)) ON (`t_country`.`ID_country` = `mt_films`.`id_country`))
        LEFT JOIN `st_critics` ON (`mt_films`.`ID_films` = `st_critics`.`ID_Films`))
        LEFT JOIN `t_film_critic` ON (`t_film_critic`.`ID_name` = `st_critics`.`ID_name`))
    WHERE
        `mt_films`.`date_out` LIKE '%2021%'
            AND `st_peoplefilms`.`ID_idiotita` = 1
            AND `mt_films`.`reissue` = 0
            AND `mt_films`.`poll` = 2
    GROUP BY `mt_films`.`Title1`
    ORDER BY `mt_films`.`date_out` , `mt_films`.`Title1`

till here everything works perfect sorting all titles alphabetically by distribution date
But when I add

Code:

case when `t_film_critic`.`film_critic` is not null then
concat('Read critics by ', group_concat(distinct '<a href="./index.php?  option=com_content&view=article&id=',
`st_critics`.`code_critics`,
'"','>\n{modal article="',
`st_critics`.`code_critics`,
'" title="',`mt_films`.`Title1`,' <br> Critic by: ',
`t_film_critic`.`name`,'" width="750" }',
`t_film_critic`.`name`,' {/modal}\n</a>'
order by `t_film_critic`.`name` ASC separator ', '))
else 'There is no available critic yet' end AS `film_critic`,

It works but without date sorting
Could you please help to find a solution?
