Answer 1

To fix this issue, you can create an empty app/etc/NonComposerComponentRegistration.php file in your Magento installation.

Answer 2

The issue has been resolved after upgrading the composer version to the latest.

sudo composer selfupdate --2
composer -v

I think the issue is with the More secure plugin execution concept of the composer.

allow-plugins is used on mqagento composer.json for secure magento code and composer 2.2.0 version might has some issue that why the issue happen.

see

"allow-plugins": {
    "dealerdirect/phpcodesniffer-composer-installer": true,
    "laminas/laminas-dependency-plugin": true,
    "magento/*": true,
    "php-http/discovery": true
},
