Hello @fredericlegrand,
you could try to use this:
wp_deregister_style( 'fontawesome' );
I found the issue
There is a cors origine error because the font awesome is force to load by naked domain (no www) only by the plugin
if preload the font as www it work fine
those files is forced to use non www
/yith-woocommerce-product-slider-carousel-premium/assets/fonts/fontawesome/fontawesome-webfont.ttf
/yith-woocommerce-product-slider-carousel-premium/assets/fonts/fontawesome/fontawesome-webfont.woff
