$customerDataObject returning empty Object in magento 2.4.7?

I have upgraded the magento from 2.4.0 to 2.4.7 latest version.
When I try to register the new customer, then it is throwing the error:
“There is already an account with this email address. If you are sure that it is your email address, click here to get your password and access your account.”

When I check the code line by line, I found that this file
“/var/www/html/protecta/vendor/magento/module-customer/Model/CustomerExtractor.php”

        return $customerDataObject;
    }
}

When I log the file_put_contents(BP.’/var/log/failed-register.log’, ‘FinalCustomerDataObject : ‘.json_encode($customerDataObject).PHP_EOL, FILE_APPEND);

Then is returning the empty value.
