Looks like this is still an issue:

ValidatingAdmissionPolicy 'gatekeeper-k8srequiredlabelsvap' with binding 'gatekeeper-all-must-have-label-scoped' denied request: failed to configure binding: paramKind kind &ParamKind{APIVersion:constraints.gatekeeper.sh/v1beta1,Kind:K8sRequiredLabelsVap,} not yet synced to use for admission
