I try to read a ros image message in simulink.

A msg type is "sensor_msgs/Image".

But i can't select msg type to "sensor_msgs/Imagae" in ROS2 Subscribe block.

however, it is selected in ROS subscribe block.

Same here,

I have also experienced similar issues. While creating a blank message of type sensor_msgs/Image, Simulink does not allow to select the message type.

I tried this on the same MATLAB version as yours and I am able to change the "Message type" to "sensor_msgs/Image" in the ROS2 block.

Looks like you are not clicking "OK" in the yellow box after selecting the "sensor_msgs/Image" option:

Once you click "OK" in the yellow box, you will defintely see the changed type.

Hope this helps!
