Ошибка sqlstate hy000 1049 unknown database

I have this error when i use php artisan migrate in my Laravel project.

[PDOException]
SQLSTATE[HY000] [1049] Unknown database 'previous_db_name'

this is my database.php file :

'default' => env('DB_CONNECTION', 'mysql'),
'connections' => [

    'mysql' => [
        'driver'    => 'mysql',
        'host'      => env('DB_HOST', 'localhost'),
        'database'  => env('DB_DATABASE', 'current_db_name'),
        'username'  => env('DB_USERNAME', 'root'),
        'password'  => env('DB_PASSWORD', ''),
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => '',
        'strict'    => false,
    ],
],

I saw this error in this question and this question but none of them was not helpful.

Создала БД на phpmyadmin , пытаюсь подключиться к ней и вывести массивом данные на экран, но сайт выдает ошибку ,что не видит базы с таким названием,пробовала все имена баз,никакую не видит.
Fatal error: Uncaught PDOException: SQLSTATE[HY000] [1049] Unknown database ‘mvc_site’ in C:wamp64wwwmodelsNews.php on line 17
PDOException: SQLSTATE[HY000] [1049] Unknown database ‘mvc_site’ in C:wamp64wwwmodelsNews.php on line 17

Вот код файла News.php

class News {
    
    public static function getNewsList(){
        //Запрос к БД 
        $host = 'localhost';
        $dbname = 'mvc_site';
        $user = 'root';
        $password = '';
        $db = new PDO ("mysql:host=$host; dbname=$dbname", $user, $password);
        
        $newsList = array();
        
        $result = $db->query('SELECT id, title, date, short_content'
                .'FROM news'
                .'ORDER BY date DESC'
                .'LIMIT 10');
        
        $i=0; 
        while ($row = $result -> fetch()){
            $newsList[$i]['id'] = $row['id'];
            $newsList[$i]['title'] = $row['title'];
            $newsList[$i]['date'] = $row['date'];
            $newsList[$i]['short_content'] = $row['short_content'];
            $i++;
        }
        return $newsList;
    }
}

17 строка это подключение PDO , подсвечивает что имя базы неверное,но все символ в символ идентично. Заранее спасибо за помощь

Обновление: я перенесла проект на open server, теперь базу видит , но не выводит данные таблицы, пишет что ошибка в цикле while , но не понимаю где там ошибка

Same exact problem with exact reported issues. Question here is whether there is a way to get SQL query for automatically creating all DBs and tables Firefly requires. That would be far more convenient. Also it would be awesome if there is docker image with integrated database engine.

Some if the errors I have got a long the way (I still haven’t succeeded installing docker image of firefly)

I’ve tried clearing cache and also have edited DB_PASSWORD To DB_T_PASSWORD as this corrected a similar issue earlier. Double checked the DB name, passwords etc & also other projects are already running also. I’m not able to figure it out.
