RSS feed not working

While my RSS feed is redirecting to feedburner, if I try to put the direct feed into a feed reader in outlook, https://soxanddawgs.com/?feed=rss2
it is telling me that the feed is not valid. After running it through the feed validator, I am getting an error that says that this is not a valid feed. The same goes for my comments feed as well. https://soxanddawgs.com/?feed=comments-rss2

what would be causing them not to work.
