I've also tested the github package above and it's worked on all the Macs I've tested it on. I have also altered the provided uninstaller script to work with the Ventura blocker, it seems it wasn't updated from the Big Sur one. After running it allows the Ventura installer to run on the Macs I've tested it on.
current_user_uid=$( echo "show State:/Users/ConsoleUser" | scutil | awk '/UID && ! /loginwindow/ { print $3 }' )
launchd_item_path="/Library/LaunchAgents/dk.envo-it.venturablocker.plist"
launchctl bootout gui/${current_user_uid} "${launchd_item_path}"
rm -f /Library/LaunchAgents/dk.envo-it.venturablocker.plist
rm -f /usr/local/bin/venturablocker
pkgutil --forget dk.envo-it.venturablocker
