In this screenshot it only shows File and Print Sharing via IPv6. To ping by IP Address v4, you need echo request IPv4. I did just check the firewall on my computer and there is an IPv4 and IPv6 for File and Print sharing, but it doesn’t show that in this screenshot in the question. So given answer is correct in this question
