In our tests using vlucas/phpdotenv v4.1.0 we had to update config/application.php from:

/**
 * Use Dotenv to set required environment variables and load .env file in root
 */
$dotenv = Dotenv\Dotenv::create($root_dir);
if (file_exists($root_dir . '/.env')) {
  $dotenv->load();
  $dotenv->required(['WP_HOME', 'WP_SITEURL']);
  if (!env('DATABASE_URL')) {
    $dotenv->required(['DB_NAME', 'DB_USER', 'DB_PASSWORD']);
  }
}

to:

/**
 * Use Dotenv to set required environment variables and load .env file in root
 */
if (file_exists($root_dir . '/.env')) {
  $dotenv = Dotenv::createMutable($root_dir);
  $dotenv->load();
  $dotenv->required(['WP_HOME', 'WP_SITEURL']);
  if (!env('DATABASE_URL')) {
    $dotenv->required(['DB_NAME', 'DB_USER', 'DB_PASSWORD']);
  }
}

In v4.1.0 the create() method requires three arguments:

 * @param \Dotenv\Repository\RepositoryInterface $repository
 * @param string|string[]                        $paths
 * @param string|null                            $file
