Welcome to the Microsoft Q&A and thank you for posting your questions here.
I understand that you are having Error code: UnexpectedDeploymentTemplateFailure, in your Azure Databricks.
- The message and content of the error have pointed out what you need to do, from your Azure portal, contact Azure Support.
- check thoroughly to remove any circular dependencies if there is any - https://learn.microsoft.com/en-us/azure/azure-resource-manager/troubleshooting/common-deployment-errors
- use validation tool to validate your syntax in Azure Resource Manager template - https://learn.microsoft.com/en-us/azure/azure-resource-manager/templates/validate-template
- Try deploying the resources in a different region or use a different VM size that is available in your current region, and you might need to upgrade to increase your quotas - https://learn.microsoft.com/en-us/answers/questions/792723/cluster-terminated-reason-azure-unexpected-deploym
- In your questions, it shows you can check any ongoing issues that can affect deployment in Azure Service Health https://aka.ms/azureservicehealth-securityadvisories
If you've tried all of the above and no breakthrough, as I have said at the top. Contact Azure Support.
