I have been using the USB printer controller utility version for MacOS <= 10.14 for a long time. After upgrading my laptop to MacOS 10.15 Catalina, I had to also upgrade the USB printer controller utility to the version for MacOS 10.15 (https://static.tp-link.com/2019/201911/20191107/TP-LINK%20USB%20Printer%20Controller%20Installer.zip). After the installation of the new version I was prompted to restart my laptop and did so. When I tried to log in again, the login progress bar got stuck about half way. There was no further progress for an hour, until I restarted my laptop in safe mode. I was able to log in successfully from safe mode, and after uninstalling the USB printer controller utility I was again able to log in from normal startup mode. Is this a known issue?
