I just installed drush using "composer require drush/drush". It ran correctly and when it completes a navigate to vendor/drush/drush/ directory where the drush.php file is located

Then I run the following command: php drush.php status and I get the following error:

Can anyone please guide me to what might be causing this?

I think your installation or class registry might be broken. Try doing the following things:

• See if drush rebuild works (if it does not, go to the next point).
• Go to your Drupal install directory and try to run composer install.
• If drush rebuild didn't work in the first step, try running it again now.
