Fatal error: Class Zend\Stdlib\Parameters contains 1 abstract method... magento 2

Fatal error: Class Zend\Stdlib\Parameters contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Serializable::unserialize) inC:\xampp\htdocs\magento2\vendor\zendframework\zend-stdlib\src\Parameters.php on line 14


Solution: To solve this solution, I have run following commands,
1. php bin/Magento setup:upgrade
2. php bin/Magento setup:static-content:deploy
3. php bin/Magento cache:clean
4. php bin/Magento cache:flush

I deleted files from Var folder as well I delete generation folder. I disable custom modules too.

Many common techniques which we try in our daily practice, I have tried but Finally, I found that it was not due to Magento's code or something. But it is due to XAMPP.

I stop apache and MySQL service and I restart both services again which fixed my problem and everything works perfectly now.

    This line fixed it for me "Many common techniques which we try in our daily practice, I have tried but Finally, I found that it was not due to Magento's code or something. But it is due to XAMPP."

    Could you please highlight this line so that many people can directly try this first.

    Thank you for this post.
