well, from within your config.php you tell Nextcloud to call the class OC_User_IMAP (at least I'm guessing that as you didn't fill in the issue template) so if you don't remove (or comment out) that section but just disable the app, Nextcloud will still try to use that class even though it isn't there anymore

Important detail. Thanks for this. Would you think there is may a need for an enhancement request for the log. So there do appear such kind of information? e.g. "User backend OC_User_IMAP mentioned in config.php not found."

Well of course that could make sense, but I don't know if it's possible. This error is generated by Nextcloud server and not the user_external app. To me it looks like a pretty generic error message, so not sure if that could be easily adapted to include a phrasing as in your example.
