Critical Uncaught Error: Call to a member function get_applied_coupons()

WordPress: 5.3.2
WooCommerce: 3.9.2

Hi I noticed the following errors in the WooCommerce logs, I saw you had another similar case and I was curious if you might have some more insight into it? The error appears in previous days’ logs, but I don’t see a pattern to it (it’s not there everyday either).
