Sorry you had that happen. This is not a normal result of installation. It's possible the Fences app got corrupted for some reason. Dis you install Fences before or after the Patch Tuesday update?
Were you eventually able to get your computer to boot?
Try uninstalling Fences and then restart. Download a fresh Fences installer from your account downloads and install. Make sure to reboot after the install finishes.
Also, What version and build of Windows are you running? What version of Fences 5 did you initially install?
