Timeout error when running robot.MoveJ in simulation mode (MacOS)

I'm trying to run a command on the simulator software and i'm getting a timeout error:

The code:
import robolink as rlk  # API to communicate with RoboDK for simulation and offline/online programming
import robodk as rdk  # Robotics toolbox for industrial robots

from robolink.robolink import RUNMODE_SIMULATE, Robolink

RUN_MODE = RUNMODE_SIMULATE  # Simulation behavior (simulate, or run on robot)

# Any interaction with RoboDK must be done through RDK:
RDK = Robolink()

robot = RDK.ItemUserPick('Select a robot', rlk.ITEM_TYPE_ROBOT)
if not robot.Valid():
   raise Exception('No robot selected or available')

home_target = RDK.Item("Home", rlk.ITEM_TYPE_TARGET)

The error:

Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 File "<path>/venv/lib/python3.7/site-packages/robolink/", line 4861, in MoveJ, self, 1, blocking)
 File "<path>/venv/lib/python3.7/site-packages/robolink/", line 952, in _moveX
 File "<path>/venv/lib/python3.7/site-packages/robolink/", line 680, in _check_status
   status = self._rec_int()
 File "<path>/venv/lib/python3.7/site-packages/robolink/", line 857, in _rec_int
   buffer = self.COM.recv(4)
socket.timeout: timed out

I verified, and i'm running in simulation mode, and i do get a response from
and from other commands that are not movement commands.

Any idea? I'll be happily providing more information. Thanks!
Can you provide the RoboDK project file?

Thanks for getting back to me - for some reason i didn't get a notification :|

Here is a minimized version of the RoboDK project file.
