Class 'Symfony\Component\EventDispatcher\Event' not found When making call to dnsService()

[logan-christensen]

In a fresh install of Laravel, running the following code:

    $client = new Rackspace(Rackspace::US_IDENTITY_ENDPOINT, [
        'username' => '{username}',
        'apiKey' => '{api_key}'
    ]);
    $dnsService = $client->dnsService();

Causes the error:
Class 'Symfony\Component\EventDispatcher\Event' not found

I'm using Laravel Version 8.12
PHP 7.4
I have symfony/event-dispatcher: ^5.1

I'm sure if it's related but when installing php-opencloud via composer I got the warning:

Package guzzle/guzzle is abandoned, you should avoid using it. Use guzzlehttp/guzzle instead.

To Reproduce

1. Install a new Laravel Project
2. Run composer require rackspace/php-opencloud:dev-master
3. Copy the code at the top of this issue into the route closure in /routes/web.php
4. Try to visit that route in the browser

I've shared the exception on flare: https://flareapp.io/share/pPvl0AY5#F55

This also fails on Lumen

Lumen (8.2.4) (Laravel Components ^8.0)
Tried with composer 2 and composer 1
PHP 7.3

Class 'Symfony\Component\EventDispatcher\Event' not found (500 Internal Server Error)

@logan-christensen I know this was raised a few years ago but did you manage to resolve the issue as ive just tried it to connect to our rackspace and getting the same error

We actually engaged their engineering team and it was pointless. We since moved to AWS. However, I was able to get curl commands to work creating DNS A records, etc.
