Network Policies

Hi guys, I installed a ServiceMeshControlPlane in my namespace on openshift. With my instance was configured some network policies related to Istio. I installed other operator in the same namespace but it is not configured with Istio. I tried to create a new resource with CRD but Error “admission plugin “MutatingAdmissionWebhook” failed to complete mutation in 13s” for field “undefined” appears. Could Istio network policies cause the error?
