RMW Implementation questions in MATLAB R2022a

Hello, I'm using the r2022a version now, and want to connect matlab and simulink with ros2.

I have already set the rmw_implementation to the same rmw_fastrtps_cpp in both matlab and ros environment, as is shown in picture.

But the matlab cannot receive any topic, when I use ros2 topic list im the matlab, and also the simulink blocks cannot receive any topic.

Do you know why I have this trouble?

This is the topics in the terminal

And this is the topics in the matlab
