After about a week, the http status code 500 errors stopped occurring, and my app started working again. I didn't make any changes during this time. It appears to be a problem with the CloudKit servers. However, it's unnerving to me that my app was not functional for a week, and I got no response on this forum, through the Feedback Assistant, or to my request for a code review.
