Plugin not working after last update

Hi,
I update Shipping Zones by Drawing for WooCommerce to the last version.
Now the shipping methods created with the plugin are not shown at checkout.
I installed a plugin that allows you to see if the shipping rules logic is respected which is called “Conditional Shipping Debug”.
This plugin finds the right shipping classes that I created but then the user who purchases does not see them.
With version 2.8.12 everything worked.
I tried deactivating the plugin and theme and nothing changed.
How can I do it?
