Ok. After hours of digging I see what has happened.

From the docs here:

• The GKE cluster cost applies even if Databricks clusters are idle. To reduce this idle-time cost, Databricks deletes the GKE cluster in your account if no Databricks Runtime clusters are active for five days. Other resources, such as VPC and GCS buckets, remain unchanged. The next time a Databricks Runtime cluster starts, Databricks recreates the GKE cluster, which adds to the initial Databricks Runtime cluster launch time. For an example of how GKE cluster deletion reduces monthly costs, let’s say you used a Databricks Runtime cluster on the first of the month but not again for the rest of the month: your GKE usage would be the five days before the idle timeout takes effect and nothing more, costing approximately $33 for the month.

The issue is, now that I want to create a new cluster in databricks, it seems databricks is unable to recreate the GKE cluster? It should not take more than an hour to recreate the GKE...?
