Once Terminal says 'Install media now available,' it is safe to right-click the removable drive on the desktop renamed 'Install macOS Catalina' and select the 'Eject' command. Download the full Catalina installer from Apple, if you don't already have it. If downloading it now, when the screen comes up to choose a volume to install Catalina to, just press Command+Q to quit out of the install. The installer itself should still be in the Applications folder. Run this command in Terminal. This occurs when the copy of the macOS Catalina Installer app used has gotten corrupted somehow. To rectify this, use Catalina Patcher to download a fresh copy of the Catalina installer, then re-create an installer volume and/or retry the installation.
