Magento 2: Error: Cannot instantiate abstract class Magento\Framework\Model\ResourceModel\AbstractRe

[Partab Saif]

I'm using Magento 2.4 and getting the following error on order submit. I did run rm -rf generated/code/* generated/metadata/* pub/static/* var/cache/* var/composer_home/* var/page_cache/* var/view_preprocessed/*
php -dmemory_limit=-1 bin/magento setup:upgrade && php -dmemory_limit=-1 bin/magento setup:di:compile && php -dmemory_limit=-1 bin/magento setup:static-content:deploy -f && php -dmemory_limit=-1 bin/magento c:c && php -dmemory_limit=-1 bin/magento c:f, but getting same error everytime.

Hello @Partab Saif 

This error belongs to constructor only. We need to pass all variables to parent class for resolve. Example :

  public function __construct(
        Context $context,
        Registry $registry,
        AbstractResource $resource = null,
        AbstractDb $resourceCollection = null,
        DateTime $dateTime,
        array $data = []
    ) {
        $this->dateTime = $dateTime;
        parent::__construct($context, $registry, $resource, $resourceCollection,$dateTime, $data);

    }

You can take reference of above code and pass variable through parent::__constructur().
please check all constructor of your files.

@Partab Saif Did you ever find a resolution for this error? I'm experiencing an identical issue after upgrading to 2.4.4p2.

Thanks for your time and feedback!

FYI - My issue was resolved when I fixed a PHP 8.1 warning: "Optional parameter is provided before required"

I just re-arranged the parameters in my __construct(...) 👍
