Poor sound Robotic Glitches NAno Cortex as an interface

I am having a huge problem when using Nano Cortex as an interface. When monitoring music from DAW or youTube to play along i am getting distorted sound and glitches on my headphones. I ve tried on mac and it is ok so I am assuming it is not Nano Cortex but Can’t set it up to work properly. i’ve installed driver and changed buffer size restarting PC etc.

same situation here
