First time portworx install - Error registering CRD's for StorageCluster controller

Hi everyone, I’m trying to install portworx 2.8 as operator on a 3-node K8S cluster (running 1.22.1), but after applying kubectl apply -f 'https://install.portworx.com/2.8?comp=pxoperator' the pod doesn’t come up and the logs are below

Does this suggest that some other software dependencies are not met? What else could I be missing?

kubectl logs portworx-operator-fdcbd8688-xcpd4 -n kube-system
