Brew openvpn-connect on macos fails to upgrade or remove

I installed openvpn-connect with brew install –cask openvpn-connect
all good
Today I run brew update; brew upgrade, there was an upgrade for openvpn-connect, the upgrade failed.
I have since tried to uninstall it completely but the uninstall fails with:

    ==> Removing launchctl service org.openvpn.helper
    ==> Running uninstall script /Applications/OpenVPN Connect/Uninstall OpenVPN Connect.app/Contents/Resources/remove.sh
    Warning: uninstall script /Applications/OpenVPN Connect/Uninstall OpenVPN Connect.app/Contents/Resources/remove.sh does not exist; skipping.

The application appears to be gone, however brew still tracks is as installed.
