iTunes will not validate

Getting this error after posting a new podcast:

Can’t parse your feed. Invalid XML: Error on line 279: The element type “itunes:summary” must be terminated by the matching end-tag “</itunes:summary>”.

Here is the feed: https://www.tbcpodcast.com/feed/podcast/

I changed nothing in iTunes between the last post and the one from a couple of weeks ago. Was there an update to SSP?
