mbed studio debugger failing

Using mbed studio 0.5.3 on Windows 10

Testing with the mbed-os-example-blinky which is loaded using the menu option: 'File -> Import Program', build profile is set to 'Debug'

Target is an EA LPC4088 Quickstart board which is connected and recognised by mbed studio.

When I click on the debug icon, the example compiles but I get the following in the Debug Console:

From a CMD console I can see that the board is recognised by pyocd:

Is there something I'm missing?
