How to uninstall and revert to Drupal core MySQL driver?

Hi, I was unable to reproduce the issue and was able to successfully remove the module via composer.Below is my settings.php file you can compare and check whether there is any issue with it.

$databases['default']['default'] = array (
  'database' => 'samdr102',
  'username' => 'root',
  'password' => 'root',
  'prefix' => '',
  'host' => 'localhost',
  'port' => '3306',
  'isolation_level' => 'READ COMMITTED',
  'driver' => 'mysql',
  'namespace' => 'Drupal\\mysql\\Driver\\Database\\mysql',
  'autoload' => 'core/modules/mysql\\src\\Driver\\Database\\mysql\\',
);

@samir I can confirm this did work for me, thanks. I had the database namespace set in my main settings.php file that was overriding what I had in a local settings file.
