It sounds like the installation didn't go correctly.
I imagine either the service is not installed or is set to not run for some reason. (some AV apps have an annoying ability to stop installations of apps working right sometimes)
You need to uninstall, reboot and then install again and hopefully all will be well.
Obviously officially we do not support insider builds but I just checked on 10.0.20175.1000 and all is well which is as I would have expected.
