[Risolto] Translation Pages/Products not working

Background of the issue:
I am trying to translate products and pages on my site link nascosto using WPML, following the same method I've used for the past four years.

Symptoms:
Anytime I try to translate a product or a page, the page freezes and nothing comes out.

Questions:
Why does the translation process freeze when I try to translate a product or page? I cannot work or do anything
