Trouble with RSS

WordPress updated a few weeks ago and ever since then, the RSS reader on my website has been unable to get the feed from my wordpress blog. The feed url I am using is https://foxvalleygivingmatters.org/feed/ and it’s the one I was using quite successfully up until a few weeks ago. The issue is not with the feed reader on our website, since it successfully reads other news rss feeds successfully. Am I using the incorrect URL for my blog? Or is it something that I can’t fix?
