Hi, I appreciate your time and your intention to help.
I have managed to uninstall all the plugins, I activate those woocommerce tools but it is not possible, they spend more than 24 hours with the message that the search tables are regenerating, the products are all variable, and yes, they are out of stock.
For example, you filter size 7us and the result shows you products that are out of stock, I see the product and yes, they are just out of stock but it should not show when I run the filter.
