Hello,
The error you are encountering is often because of your model or environment still has some reference to that file, even if you think you have removed it. This can be due to internal caches or metadata that have not been fully reset.
Following are a few troubleshooting steps to counter this issue:
- Open your model and review its properties (File > Model Properties > External Data or via Model Explorer) to see if there’s still a reference to "my_dict.sldd". Remove it if found.
- Clear Simulink dictionary cache by running the following command in MATLAB. Then restart MATLAB to ensure caches are cleared.
>> Simulink.data.dictionary.closeAll
If you are still encountering the issue, I would suggest you reach out to MathWorks Technical Support: https://www.mathworks.com/support/contact_us.html
