Unable to link PX4 Simulink file to real board OR SITL with JMAVSIM

Hi everyone, I am having an issue running the Simulink PX4 GPS demo on my real board (CubeOrange) or in simulation. When attempting to run with connected IO I get the error below - both for the real board or in simulation. I have no idea what might be causing it.

MATLAB System block 'PX4/GPS/PX4 uORB Read/SourceBlock' error occurred when invoking 'setupImpl' method of 'px4.internal.block.Subscriber'. The error was thrown from '

'/root/Documents/MATLAB/SupportPackages/R2023b/toolbox/target/supportpackages/px4/+px4/+internal/+block/Subscriber.p' at line 196

'/usr/local/MATLAB/R2023b/toolbox/target/codertarget/sltoolstrip/m/+codertarget/+sltoolstrip/EmbeddedHardwareBoardContext.m' at line 523'.

Can you upgrade to MATLAB R2024a and see if you are still running into this issue?
