Magento 2 Sales Order Items in Custom Email

I have created custom email template and calling order item in it. In my site I’m adding or editing the specific order Item and I need need to send email for that item only. It was working fine in the Magento 2.4.3. Now I have upgraded to 2.4.6-p1 and it’s giving error when going to send the email.
