I am trying to create a ROS2 node on Windows 11, MATLAB R2025b.
While either trying to create a node, or even testing with "ros2 node list", I receive an error:
>> node = ros2node("matlab_node");
Error using ros2node/createNode (line 552)
Error creating the ROS 2 node matlab_node.
Error in
ros2node (line 166)
createNode(obj, parser.Results.name, parser.Results.id);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Caused by:
Error using
ros.internal.Node/create
Server failed to start. Details: Transport stopped.
This was working hours ago...
reinstalling ROS toolbox and even MATLAB did not change outcome.
Thanks!

I found a soludtion. "This error is shown when some shared memory files have not been correctly freed if the Fast DDS application has crashed or has not been closed cleanly. Fast DDS CLI provides an option to clean zombie files: fastdds shm clean. The issue is that if the file is still blocked because Fast DDS was closed unexpectedly then this tool cannot remove the file. Then, the only option is to remove these files manually. The shared memory files are saved in the following folders and are named with fastrtps included in their filenames:"
[RTPS_TRANSPORT_SHM Error] Failed init_port fastrtps_port7415: open_and_lock_file failed -> Function open_port_internal [13645] · Issue #2003 · eProsima/Fast-DDS
The solution involved deleting the shared memory files as described in the link.
