Hi Rim,

From the error you have mentioned here, it seems like you have a Simulink model which has a library block inside. It seems like you have a script in the InitFcn callback that is modifying the structure of this library block.

Please remember that you have to disable the locked link of this block to the library before making any changes to it.

1. Remove the lock from the library

2. Disable the library link

3. Run your model

This should fix your issue.
