Try to verify that the fine-tuning process completed successfully and that the model files are correct. You can have more information if you review Azure Activity Logs, Application Insights, or Log Analytics for any hidden errors or warnings that might indicate the issue.
If the problem persists, try canceling and retrying the deployment, as transient issues can sometimes cause delays. If all else fails, contact Azure Support with detailed logs and deployment information for further assistance.
