The issue is that #2659 hard-codes the expected name of the ClusterRole, while at https://github.com/kyverno/kyverno/blob/main/charts/kyverno/templates/clusterrole.yaml#L20-L24 it is dynamic.

@diranged We are planning to add extra Label to ClusterRole and will get ClusterRole from that instead of hardcoding it fix this issue. Will this solution works for you?
