- Check for Duplicate Block Diagrams - Make sure that you don't have multiple instances of the same block diagram within your Simulink model. Duplicate block diagrams can lead to this error.
- Review Block Diagram Registration - Check your model's initialization code or any custom scripts you've written to register block diagrams or handlers.
- Clear Simulink cache and restart Simulink.
Error handler must not already be registered: blockDiagram
