CRITICAL Uncaught Error when setting order status to ‘Processing’

CRITICAL Uncaught Error: Call to a member function get_cart() on null in [...]/plugins/woo-mailerlite/includes/functions.php:1632

Happens when changing an order status to ‘Processing’. Using version 1.7.15.

Looking through the code, it seems to be checking for the cart. In an admin context when you’re processing an order, there is no cart so this seems a bit redundant.

Other info:
WP: 6.1.1
WooCommerce: 7.1.0
Woo MailerLite: 1.7.15
All other plugins disabled.
