mdd command line debug timeout loading prg app

Per the documentation for ConnectIQ 3.2, it should be possible to use mdd as a command line debugger

mdd --help
usage: mdd [-d <arg>] [-e <arg>] [-h] [-x <arg>]
-d,--device <arg>    Device to simulate
-e,--executable <arg>CIQ executable (PRG) to debug
-h,--help            Print help message
-x,--debug-xml <arg> CIQ debug.xml of the provided PRG

For me, mdd mostly times out while loading the prg file.

There is a set timeout command (below) but this does not appear to change the behavour from the mdd command line or the file command within a session

(mdd) help set timeout
Set timeout limit to wait for the CIQ virtual machine to respond to NUM seconds.
Usage: set timeout NUM.

----------------------------------------------------------------------------------

(mdd) help file
Set the target executable, debug.xml, and device to simulate.
Usage: file EXECUTABLE DEBUG_XML DEVICE_ID
EXECUTABLE is a Connect IQ executable to run.
DEBUG_XML is the debug.xml generated during app compilation.
DEVICE_ID is the device to simulate.

File paths can have spaces as long as the path is wrapped in quotes.

For example

(mdd) set timeout 5000

(mdd) show timeout
The timeout limit is 5000 second(s).

(mdd) file bin/myApp.prg bin/myApp.prg.debug.xml edge520plus

Loading app: path_to_app\bin\myApp.prg

Failed to launch the app: Timeout

timeout occurs after roughly one second

The same for the command line directly:

mdd -d edge520plus -e bin/myApp.prg -x bin/myApp.prg.debug.xml
Connect IQ Version 3.2.5. Type "help" for more information.

Loading app: path_to_app\bin\myApp.prg

Failed to launch the device: Timeout
(mdd) quit

There are no spaces in the filenanes and I've tried with forward slashes and backward slashes
