Laravel 8: QueueManager.php:156 array offset of type null / Configure redis

Question

I am about to setup Redis and Laravel Horizon. Although I have set up everything correctly (I assume) I get a very weird error. Laravel tells me that it is Trying to access array offset on value of type null at vendor/laravel/framework/src/Illuminate/Queue/QueueManager.php:156

The line 156 is the first return line:

/**
* Resolve a queue connection.
*
* @param  string  $name
* @return \Illuminate\Contracts\Queue\Queue
*/
protected function resolve($name)
{
    $config = $this->getConfig($name);

    return $this->getConnector($config['driver']) // <-- This line
                    ->connect($config)
                    ->setConnectionName($name);
}

So, I assume Laravel cannot access $config['driver']. But when I do a dd of $config I get the following:

array:5 [
  "driver" => "redis"
  "connection" => "default"
  "queue" => "default"
  "retry_after" => 90
  "block_for" => null
]

So, it is impossible that driver is empty because as you can see driver is set to redis. Do you guys have any idea why Laravel cannot access array offset on value of type null?

I have installed phpredis, a Redis database and also Laravel Horizon. When I try to access my /horizon I get the same error as above.

phpredis is installed correctly. I have added extension=redis.so to my php.ini and when I execute php -r "if (new Redis() == true){ echo \" OK \"; }" in my command line I also get OK. So, it cannot be phpredis.

My Redis database is also working:

$ redis-cli
127.0.0.1:6379> ping
PONG
127.0.0.1:6379>

And my configs are also correct. This is my .env (just some entries):

APP_ENV=local
APP_DEBUG=true

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel
DB_USERNAME=root
DB_PASSWORD=password

BROADCAST_DRIVER=log
CACHE_DRIVER=file
QUEUE_CONNECTION=redis
SESSION_DRIVER=file
SESSION_LIFETIME=120

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

Here is my config/queue.php:

 env('QUEUE_CONNECTION', 'sync'),

Anyone has an idea why I get this error? I am working on php 7.4.16, 10.5.6-MariaDB, redis-cli 6.2.1 and on Laravel Framework 8.32.1. So, everything is on the newest version.

I would appreciate any kind of help! Kind regards
