Hi All, I'm trying to install a new rancher 2.7.2 cluster on top of a freshly installed rke2 1.25.7 cluster. I'm following the air-gapped install instructions for rancher 2.7 but I must be missing something because when I get to the install rancher step it fails with an error about PSP missing:

"Error: INSTALLATION FAILED: execution error at (rancher/templates/validate-psp-install.yaml:4:5): The target cluster does not have the PodSecurityPolicy API resource. Please disable PSPs in this chart before proceeding."

If I add the "global.cattle.psp.enabled=false" flag, I get an other error:

INSTALLATION FAILED: unable to build kubernetes objects from release manifest: resource mapping not found for name: "rancher" namespace: "" from "": no matches for kind "Issuer" in version "<http://cert-manager.io/v1alpha2|cert-manager.io/v1alpha2>" Ensure CRDs are installed first

Can someone please suggest what I am missing?
