For those who were affected by the ‘9DCE38C9695E’ error message, we’re happy to report we’ve fixed this and messages can be sent once again. If the error persists, performing a hard refresh of the app with Cmd/Ctrl+Shift+R should get things in order.

We’re sorry for the interruption to your day and if you continue to experience any issues, please reach out to us at feedback@slack.com.
