@apfelbox @franzliedke could you please look into this PR / issue?

meanwile, this is how I used this PR locally as a global installation:

nano ~/.composer/composer.json

and override content with

{
    "require": {
        "franzl/studio": "dev-php8support"
    },
    "config": {
        "allow-plugins": {
            "franzl/studio": true
        }
    },
    "repositories": [
        {
            "type": "vcs",
            "url": "https://github.com/head1328/studio/"
        }
    ]
}

then

composer global update franzl/studio

---

I can confirm that studio works on PHP 8.3 with this PR

Please can you also add Symfony 7.x support to this otherwise even if this is merged we are going to run into the next hurdle almost immediately. Thanks.
