The Kubernetes cluster is created by CLI last year.
When I import it into terraform, the value of fields run_command_enabled and private_cluster_public_fqdn_enabled is null.
Now, I can not update the cluster via terraform, even ignore these two fields or declare the fields to default value explicitly.

Error: The terraform-provider-azurerm_v3.7.0_x5 plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.
