Hi,

I understand that you faced a build issue while performing SITL on Windows 11 with jMAVSim using UAV Toolbox Support Package for PX4 Autopilots. This may occur if you run ‘Build Load and Run’ instead of running ‘Monitor and Tune’ operation.

I advise you to follow the instructions provided under Task 3 in the ensuing documentation:

You can also refer to the following MATLAB answer for more information :

Hope this helps!
