Hi @Hauser, Kevin , Thanks for using Microsoft Q&A Platform.
This can be due to the Azure Search service error that is used by Language Studio to store and search your knowledge base. As suggested by the error message Azure Search service may not be running or may not be configured correctly.
To check that the Azure Search service is running. Navigate to the Azure portal and to your language resource. You should see the status of the Azure Search service.
Or you can directly navigate to the Azure search service resource and under the "Overview" section, you should see the status of the Azure Search service as Status: Running. If the service is not running, try restarting it.
Could you please verify this status and let us know?
I hope this helps.
Regards,
Vasavi
