Hi  
I am getting the following error after updating the Shopware from 6.3 to 6.4

`There is no extension able to load the configuration for "swiftmailer" (in "/var/www/html/biberna-staging/vendor/shopware/core/Framework/Resources/config/packages/swiftmailer.yaml"). Looked for namespace "swiftmailer", found ""framework", "monolog", "sensio_framework_extra", "twig", "web_profiler", "debug", "enqueue", "enqueue_adapter", "shopware", "storefront", "elasticsearch"" in /var/www/html/biberna-staging/vendor/shopware/core/Framework/Resources/config/packages/swiftmailer.yaml (which is loaded in resource "/var/www/html/biberna-staging/vendor/shopware/core/Framework/Resources/config/packages/swiftmailer.yaml").`

How we can fix this?

Delete that swiftmailer.yaml files from the following path

/vendor/shopware/core/Framework/Resources/config/packages/swiftmailer.yaml

/vendor/shopware/core/Framework/Resources/config/packages/dev/swiftmailer.yaml

that files should be automatically deleted during installation.

Deleting of those files generates new errors.  
any solution’?
