Such error message, particularly the exception shown in the 2nd screenshot, indicates that the "Email address for Site Alerts" setting was either empty, or multiple email addresses were specified, incorrectly.
Please go to App Portal Admin > Site Management > Settings > Email, at the "Email Address for Site Alerts" section, remove all the email address specified and provide only one email id and click on save. (This field should not be blank)
Once a valid Email address is input, it should stop the ESDService from crashing. If not, please contact support for further assistance.
