Describe the bug

While creating tanzu-mission-control_tanzu_kubernetes_cluster, Terraform crashed after ~8 mins with the following error. Even if terraform crashed, the clusters were created in TMC.

Error: The terraform-provider-tanzu-mission-control_v1.4.3 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.

Reproduction steps

Unknown

I applied the terraform module several times in clean environments and I got this error only once
source code is available here https://github.com/giovannibaratta/vmware-tanzu-training/tree/main/terraform/stages/50-tmc

Expected behavior

The plugin should not crash

Additional context

• I am using TMC self managed v1.1
• MacBook M1
