Stopped working

Hi, the plugin worked well for me all the time, until one day it stopped working, what do you mean it stopped working? It doesn’t show x’s on variations of products that are out of stock…. It doesn’t even connect to WooCommerce’s settings, when I go into WooCommerce’s settings, the plugin doesn’t appear. Does anyone know the reason? The most updated WordPress and all plugins are updated so far 8.8.2022
