Whenever anyone tries to view the "Application Builder" in our APEX install which is using the standalone listener (v. 18.104.22.168.11.40), they get a blank page.
It seems to be the same error as described at Page get blank when click application builder - but we are using the standalone listener, and have restarted the listener to no avail.
