Fatal error due to trailing comma

    $configImporter = new ConfigImporter(
      $storageComparer,
      $this->eventDispatcher,
      $this->configManager,
      $this->lock,
      $this->configTyped,
      $this->moduleHandler,
      $this->moduleInstaller,
      $this->themeHandler,
      $this->stringTranslation,
      $this->extensionListModule,
    );

There's a trailing comma after $this->extensionListModule,
