Post Rancher 2.5.9 upgrade - can't remove imported GKE cluster

Hi, I recently upgraded Rancher (cluster hosted in Google Cloud) from 2.14.3 to 2.5.9. When trying remove an imported k8’s cluster, also created in GCP, I get the following error in the Rancher UI:

This cluster is currently Removing ; areas that interact directly with it will not be available until the API is ready. Failed to communicate with API server during namespace check: Get “”: context canceled; waiting on cluster-scoped-gc

If anyone has seen this issue, or knows how to address, I’d appreciate it! I’ve tried to remove using the Rancher CLI with no luck. I’ve also tried to re-import that same cluster which fails…
