When custom cancels their subscription, fatal error occurs and this appears in the error.log like this example:
CRITICAL Allowed memory size of 268435456 bytes exhausted (tried to allocate 528384 bytes) in /www/websitename/public/wp-content/plugins/woocommerce/includes/emails/class-wc-email.php on line 447
To Reproduce
Error seems to always point to line 447 or sometimes 449 of class-wc-email.php
Customer cancels subscription
They do not receive the cancellation confirmation email due to the fatal error
Expected behavior
Actual behavior
These are the lines of code triggering it. I have 256MB of memory allocated, so this should not be happening:

BY RESULTING IN AN INFINITE LOOP APPENDING THE CUSTOMER EMAIL TO THE RECIPIENTS INFINITE TIMES:
add_filter('woocommerce_email_recipient_cancelled_subscription', 'set_customer_as_cancelled_subscription_recipient', 10, 2);
function set_customer_as_cancelled_subscription_recipient($recipient, $subscription) {
//this line makes the customer the only recipient
// return $subscription ? $subscription->get_billing_email() : $recipient;
//this appends the customer as a recipient in addition to the recipient specified in WooCommerce Email settings
if ($subscription && false === strpos($recipient, $subscription->get_billing_email())) {
// Append the customer's billing email to the existing recipient list, separated by a comma
$recipient .= ',' . $subscription->get_billing_email();
}
return $recipient;
}

THIS APPEARS TO WORK AS OF JAN 2024:
