Pimcore cannot write and read the object with object bricks

Actual behavior

PHP Fatal error: Uncaught TypeError: Cannot assign Pimcore\Model\Element\ElementDescriptor to property Pimcore\Model\DataObject\Objectbrick::$object of type ?Pimcore\Model\DataObject\Concrete in /var/www/vendor/myclabs/deep-copy/src/DeepCopy/DeepCopy.php:253
