Sorry to hear that you're having trouble. Can you confirm that the system extensions are loaded correctly and that the endpoint was rebooted after install?
After a reboot, if it's still not working an SDU would help us with our investigation. Please provide an SDU from the affected machine by following these steps:
Go into Central, find the device, and click on the generate SDU button
Once the sdu is uploaded, post the file name here so we can extract it and take a look
