Update caused issue

I’m using this code in some custom templates:

$brands = \Perfect_Woocommerce_Brands\Perfect_Woocommerce_Brands::get_brands($hide_empty, 'name', 'ASC');

This has always worked, but just updated the plugin (last updated about 4 weeks ago), and it now throws a critical error.

Haven’t had a change to investigate it yet, but rolling back the plugin fixed it
