Hi Hasaan,
Are you using ROS1 or ROS2 ?
ROS2 does not require rosinit. the rosinit is for connecting to ROS1 Master.
In case of ROS2, you need to make sure that Domain ID is same. I guess in your case, the Domain ID of VM and MATLAB is same. That is why you see ros2 topic list working.
Can you provide clear reproduction steps
Thanks,

im facing the similar issue you have posted. i made a custom message using "ros2genmsg()" and when i run the simulink model i get a error message saying
STD exception 'mwboost::wrapexcept<mwboost::exception_detail::current_exception_std_exception_wrapper<std::invalid_argument> >': 'Connection to process with Exchange: "5f1470ff-8f66-40e9-84fb-5f3bfd116a13 " was lost.' was caught.
it would be thankful of you if you can share how you made it work.

Looks like restarting the MATLAB solved the problem.

I came across the same error and restrating the MATLAB didn't solve the problem. I then reset the publisher and subscriber block and it solved the error.

Hi Jagadeesh,
What I meant by reseting publisher & subscriber block is by reloading the topic in the blocks.
