No Pickup point on Checkout — Error loading shm.js on Woocommerce checkout

For a rather large client of ours, we have a webshop. On the checkout page we no longer have an option to select a bpost pickup-point.

When looking at the console logs, we found several errors.

Uncaught TypeError: a is undefined

WordPress 6.1, Woocommerce 7.6.1 and Bpost Shipping 2.3.32

This is rather urgent because clients of the webshop can no longer select a pickup-point…
