How does your rector.php look like?
It should use aRectorConfig class

[ahmedesa]

this is my rector file
`<?php

declare(strict_types=1);

use Rector\Core\Configuration\Option;
use Rector\Php80\Rector\Class_\ClassPropertyAssignToConstructorPromotionRector;
use Rector\Set\ValueObject\SetList;
use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;

return static function (ContainerConfigurator $containerConfigurator): void {
// get parameters
$parameters = $containerConfigurator->parameters();

$parameters->set(Option::AUTO_IMPORT_NAMES, true);
$parameters->set(Option::PHPSTAN_FOR_RECTOR_PATH, __DIR__ . './phpstan.neon');
$parameters->set(Option::PATHS, [
    __DIR__ . '/src',
    __DIR__ . '/tests'
]);

// Define what rule sets will be applied, run one by one, commit each time, makes reverting changes a lot easier
$containerConfigurator->import(SetList::CODE_QUALITY);
$containerConfigurator->import(SetList::PHP_80);
$containerConfigurator->import(SetList::DEAD_CODE);
$containerConfigurator->import(SetList::TYPE_DECLARATION);

};
`

You need to update config to use RectorConfig class:

<?php

declare(strict_types=1);

use Rector\Set\ValueObject\SetList;
use Rector\Config\RectorConfig;

return static function (RectorConfig $rectorConfig): void {
    $rectorConfig->importNames();
    $rectorConfig->phpstanConfig(__DIR__ . './phpstan.neon');
    $rectorConfig->paths([
        __DIR__ . '/src',
        __DIR__ . '/tests',        
    ]);

    $rectorConfig->sets([
        SetList::CODE_QUALITY,
        SetList::PHP_80,
        SetList::DEAD_CODE,
        SetList::TYPE_DECLARATION
    ]);
};
