下記修正を行えば正常に戻ります。

`src\Eccube\Twig\Extension\TemplateEventExtension.php line:67
`

修正前
`->write('$__eccube__newTemplate->display($__eccube__event->getParameters());')
`

修正後
`->write('$__eccube__newTemplate->display($__eccube__event->getParameters(), $blocks);')
`

### 再現手順(Procedure)

下記Event.phpをCustomizeフォルダに置いて、トップページを表示すると再現されます。

```
twig = $twig;
}

/**
* @return array
*/
public static function getSubscribedEvents()
{
return [
'@admin/default_frame.twig' => 'onAdminFrameTwig',
];
}

public function onAdminFrameTwig(TemplateEvent $event)
{
$source = $event->getSource();
$event->setSource($source . 'any change');
}

}

```
