Having issues with php artisan config:cache, saying it's unserializable? Say no more!

1. Remove any objects from config/logger.php. See below.
2. Inject mailer dependencies with AppServiceProvider.php
3. Note: env() variables does not work in AppServiceProvider.php. Define your variables somewhere, then use config() to access them.

$mailer and $email variables are the given class' (defined in when()) constructor arguments.

public function __construct($mailer, Email|Closure $email, int|string|Level $level = Level::Error, bool $bubble = true)
