Fast Restart can not be enabled as profiling is turned on

I have a simulink model that runs fine otherwise. But when I started to try the 'Fast Restart' feature, it gives the following warning:

Fast Restart mode cannot be enabled for model 'models' for the following reasons:
Component:Simulink | Category:Model warning
Fast Restart can not be enabled as profiling is turned on.
Component:Simulink | Category:Model warning

I am sure that I'm not in the Simulink Profiler mode, however this warning does not go away. Any ideas? Version is MATLAB 2021b.

p.s. I am aware that Fast Restart is not compatible with Simulink Profiler, as documented here. But I am not using Simulink Profiler, why is there a conflict?

I solved my own problem. The problem was that somehow the Simulink profiler was on in the background, and to manually turn it off, I used :

set_param(gcs,'Profile','off');

And then restart the simulink model, it worked.
