Call to a member function trigger() on int

Hi, We’re still having problems with our multisite running WordPress 6.6.1 & PHP 8.3.

Emailing doesn’t work and the offending lines seem to be lines 95, 96 here:

https://plugins.trac.projectdmc.org/browser/customer-address-change-notification-for-woocommerce/trunk/address-change-notification.php

95 $email = include(__DIR__.'/includes/email.php');
96 $email->trigger($customerId, $customer, $this->addressUpdatedCustomerIds[$customerId]);

Which result in a “Call to a member function trigger() on int” error. This error is eaten up silently by plugin, but I got it through debugging.

Changing the lines to this seemed to work on our case:

include(__DIR__.'/includes/email.php');
$email = new Email();
$email->trigger($customerId, $customer, $this->addressUpdatedCustomerIds[$customerId]);
