Failed to show icons with font awesom

I allow myself to send a message on the forum because I still can't find a solution to my problem! Indeed, I cannot load and display the icons on my PC, whether in localhost or on one of my online sites, no icon is displayed. While on my phone, locally and on my sites I can see the icons. I didn't change anything, it happened to me overnight. Do you know where it can come from? Thanks to anyone who can help me, and have a nice day ! (I own Font Awesome Free, and it's the same setup as when it still worked)
