I am trying to use Mozilla VPN on my Windows 10 machine but recently the program has become quite evasive. Once the program has been started, no program window appears, leaving only the taskbar notification icon. When mousing over the notification icon, the icon disappears. Despite this, the program is still reported to be running as a background process ion Task Manager, and the status of my network connection does not change throughout this process. In addition, neither starting/stopping/restarting the MozillaVPNBroker service nor running the program as an administrator seem to have any effect. I have already restarted the system, uninstalled and reinstalled the program multiple times, and performed a network reset. How can I get the program to work again?
