I am facing an issue with email sending. I am using Magento 2.4.2-p1 version. Email not sending and when I try to check emails Queue list I am getting an error message starting with - "Error: Object of class Magento\Customer\Model\Data\Customer could not be converted to string in ../vendor/magento/framework/Escaper.php:78 Stack trace: #0"
So please if know why it happened, help me. And also if the newer version you have, please upload newer version, maybe in newer version the error will not get.
