Background of the issue:

When attempting to add a manual order, I receive the message: 'There has been a critical error on this website.' I identified WooCommerce Multilingual & Multicurrency as the problematic plugin by deactivating all plugins and reactivating them one by one.

How can I resolve the conflict between WooCommerce Multilingual & Multicurrency and WooPayments?
What steps should I take to prevent the critical error when adding a manual order?
