Error retrieving device properties for persistent device - android-studio

Question

While i can compile and run to an Emulator ... i cannot do so to my hard device .. but have been able to in the past. Since then i have had to reinstall both AS and Intellij and now i get this message when attempting to install on my PixelXL
⣾Error retrieving device properties for ro.product.cpu.abi:
error: insufficient permissions for device
See [http://developer.android.com/tools/device.html] for more information
I have been to the link provided and followed instructions, but still no joy.
