I have this issue on build 18.6.2540. I'm turning the firewall off by going to Settings, Components, toggling the Firewall switch to off (Red) and selecting Stop Permanently but the firewall keeps turning itself back on after some period of time! Not only that, but when it does, it blocks my outbound traffic so I can't use remote desktop! Is there any way to keep the firewall turned off or uninstall it?
