Describe the issue

Sorry for the lack of details. After updating to 1.21.3 today, the software was complaining of a configuration error. Sadly, I was unable to find the configuration file or understand what it was complaining about. I had to restore a full backup and will skip this update. Happy to have you reach out for questions.
