I recently upgraded from Symfony 6.2 to 6.3 on both my development and production servers, and everything went swimmingly up until the point that I needed to clear the cache on the product server, whereupon I received the following output.
$ php bin/console cache:clear --env=prod
// Clearing the cache for the prod environment with debug false

[OK] Cache for the "prod" environment (debug=false) was successfully cleared.
This then makes the production server respond to all requests with a 500 Internal Server Error, and the only way to fix it is to rm -rf /var/cache/prod/* and clear the cache again.
I have gone through every single file in vendor/symfony/doctrine-bundle, vendor/doctrine folders, and removed any files that are no longer present on the development server (which went through the normal composer update process), I also checked that all the new and updated files were present (which they are).
I'm not sure where to look next to fix this issue, I include my composer.json file below:
