Hey guys,
I am facing this issue on GCP. Was wondering if it could be because of this?

Error: UPGRADE FAILED: current release manifest contains removed kubernetes api(s) for this kubernetes version and it is therefore unable to build the kubernetes objects for performing the diff. error from kubernetes: unable to recognize "": no matches for kind "PodDisruptionBudget" in version "policy/v1beta1"
