I joined just to give you a heads up in case you were still looking for the root cause, or as much of a root cause as we've gotten so far until Microsoft comments on what happened. Selecting to use the "Latest Version" upon install on your configuration XML created manually or via the Office Deployment tool and site no longer works. Microsoft may have either broken logic on the installer, or the "Latest Version" URI or CDN location or description can no longer be verified by the installer. For now, the workaround fix is to pick a specific version to install in either the XML configuration file, or if you're using Intune, change from Latest and choose a specific version in the integrated Intune Line of Business Office Office 365 Apps deployment.
