Hello.
I'm currently studying the PX4 toolbox.
I'm trying to work with the model shown in the example, but I keep encountering the following error.
What could be causing this error?

Ensure that you have built the PX4 Host Target using the hardware setup screens without errros. Once the build is successful, in Simulink ensure that you do a model update (Cntrl+D) before building. Not sure if this can resolve it but give it a try.
It will be good to understand which version of MATLAB you are using. If you are using R2024a with PX4 v1.14, since the host target will be launched inside WSL2 and the Simulink plant model will be in your host machine. For Windows machines this will result in connection issues between plant and controller. Although this is not the issue you are facing I mentioned this since you might face the connection issue after resolving the current issue.
You can also consider giving a try with the rate controller example and see if you are facing any issues there.
