This thread is resolved. Here is a description of the problem and solution.

Problem:
If you're experiencing a critical error on your website after activating WooCommerce Multilingual & Multicurrency, it might be due to using an outdated version of WooCommerce.

The problem is that you are using a really outdated version of WooCommerce 3.7.0 and the last one is the 9.8.4. I have updated WooCommerce and the install WooCommerce Multilingual and it works on the local site. So you will need to update first WooCommerce and then install WooCommerce Multilingual. Please let me know if you have any problem.

As I said on this answer: https://wpml.org/forums/topic/when-i-active-woocommerce-multilingual-multicurrency-my-website-was-broke-its-says-critical-error/#post-17003038 the problem is that you are using a really old version of WooCommerce, so you need to update WooCommerce to the latest version.
