Why can't I restore disabled links from a model StopFcn callback?

I have a model, where I want to disable links before the simulation and to restore the links after the simulation.

The InitFcn callback looks like this: set_param('BreakLinks/LibraryBlock', 'LinkStatus', 'inactive')

It works, the link is disabled. In the same model, the StopFcn callback looks like this: set_param('BreakLinks/LibraryBlock', 'LinkStatus', 'restore')

The link is not restored by the StopFcn. Why not? How can I work around this problem?

It could be because executing StopFcn is also part of simulation. And you can not modify the library link of a block during the simulation process.

Simulation Started --> Execution --> Simulation stopped --> Save Workspace data --> Execute StopFcn --> Simulation finished.

You can modify the links only after simulation is finished.

You can restore the library in save or close callback functions.

Thank you for a clarifying answer. I can probably use the save callback instead.
