I have a D10 Commerce site that I installed the module on, once I configured a registration type, I immediately started getting this error on any page that seems to be trying to load a cart:
TypeError: Drupal\registration\RegistrationHostEntityHandler::createHostEntity(): Argument #1 ($entity) must be of type Drupal\Core\Entity\EntityInterface, null given, called in /var/www/html/web/modules/contrib/commerce_registration/src/OrderProcessor/RegistrationOrderProcessor.php on line 47 in Drupal\registration\RegistrationHostEntityHandler->createHostEntity() (line 21 of modules/contrib/registration/src/RegistrationHostEntityHandler.php).

I think the steps here are to have a WIP cart when installing the module. In this case it's because I have an admin cart from messing around with Commerce Kickstart. I believe that cart may have a reference to a deleted product in it.
I'll probably resolve this by cleaning up that cart from the command line or something, or possibly uninstall the module, clean it up, then reinstall, but I believe the module code could avoid erroring with some checks in the referenced code.
Simply changing those lines to this:
<?php
/** @var \Drupal\commerce_product\Entity\ProductVariationInterface $variation */
$variation = $item->getPurchasedEntity();
if ($variation) {
$host_entity = $handler->createHostEntity($variation);
}
?>removes the fatal error.
Decide what direction is desired to fix this edge case.

Just realized this is a dupe of https://www.drupal.org/project/commerce_registration/issues/3382143 🐛 Null argument exception in cart after deletion of product variation Fixed , I'll see if I can install the dev version and I'll close this issue, sorry for the noise!
