Steps to reproduce the issue

Installing Joomla 3.9 (from 3.8.13) using built-in Joomla Update. Clicked normal blue "Install the Update" button.

Expected result

Notice of successful upgrade from 3.8.13 to 3.9.0

Actual result

Receive error message: "Error: 0 Class 'JToolbarHelper not found'. There is a button to return to the Control Panel. Pushing the button just re-displays the same screen. Joomla menu is visible (System, Users, Menu, etc.). No matter what option I select, this same screen re-displays.

System information (as much as possible)

From Joomla Update log file:

2018-10-30T15:16:44+00:00 INFO 184.182.14.245 update Update started by user Super User (XXX). Old version is 3.8.13.

Additional comments

Website is still running apparently okay. But no access to the backend to maintain.

I pointed this out several months ago. There was a release blocker label on #21960
