Message: "no products match your search" after enfold and wordpress update

Hello
I just changed version
   – enfold 4.6.3.1 to 4.7.5
   – WordPress 5.3.3 to 5.4.1
   – woocommerce 4.1.1
with the old and new versions everything works correctly, with the use of the product sliders and product grid.
but if I update a page with products, the products no longer appear (message “no products match your search”); whereas for the pages that I haven’t touched, it works.
I selected the classic editor and not the block editor in enfold child
I am going back to wordpress version 5.3.3 but the problem is the same.
While waiting for a fix, how do I get back to version 4.6.3.1 of enfold?

thank you in advance for your response
