Making Terraform destroy Idempotent when using remote state

I have 2 workspaces (workspace_aworkspace_b) in TFC that I plan/apply and destroy as part of GitHub Actions pipeline.

workspace_b uses remote state from workspace_a:

First time I run the destroy pipeline: destroy workspace_b followed by destroy workspace_a everything is fine.

However if I re-run the destroy pipeline it fails because terraform cannot lookup the remote state of workspace_a.

What’s the best way to make the pipeline Idempotent so we can re-run destroy without data.terraform_remote_state failing?
