Hi 
I want to use ACADOS in MATLAB to implement NMPC for UAV control. I have already configured the MATLAB-ACADOS environment, and I can successfully run the provided examples. However, when I try to run my own code, I encounter an error indicating a file permission issue. How can I resolve this?
error message：
nmpc_load_position_acados_create() → success!
delete template…
done.

Successfully rendered acados templates!
