"Unable to run bin/magento In some cases after running the composer upgrade you may find yourself unable to run bin/magento on the command line, and instead get the following error

An abstract factory could not create an instance of magentoframeworkappdeploymentconfig(alias: Magento\Framework\App\DeploymentConfig).

This is due to the setup folder not being updated, which means it still has references to the Zend Framework packages rather than the new Laminas ones.

The way to fix this is to use composer to create a new Magento 2 project and then copy the setup folder from there in to the code base. Make sure any changes that you have made to the directory are applied and then the command should work"

In my case I just copied the setup folder of another working magento installation over mine. I also noticed that all modules were disabled. So I had to enable them

php bin/magento module:enable --all && php bin/magento setup:upgrade && php bin/magento setup:di:compile && php bin/magento setup:static-content:deploy de_DE && php bin/magento setup:static-content:deploy

You can't instantiate an object of form without passing argument. Please refer file Magento\Framework\Data\Form.php wherein construct function there are four arguments (one is an array) so you must pass three arguments during initiate object of Form:

 class Form extends \Magento\Framework\Data\Form\AbstractForm
 {
     public function __construct(
         Factory $factoryElement,
         ElementCollectionFactory $factoryCollection,
         FormKey $formKey,
         $data = []
     ) {
         parent::__construct($factoryElement, $factoryCollection, $data);
         $this->_allElements = $this->_factoryCollection-create(['container' => $this]);
         $this->formKey = $formKey;
     }
 }

Your argument is not matching with construct function.
