Describe the bug:
When the model fails to load, the local API server starts, but the "API Reference" button is missing from the interface.

Steps to reproduce:

1. Open local API server in the application.
2. Intentionally cause the model to fail to load.
3. Observe that the local API server has started.
4. Look for the "API Reference" button in the interface.

Expected behavior:
When the model fails to load and the local API server starts, the "API Reference" button should still be present in the interface.
