 EKS managed node groups on `v18.x` by default create a security group that does not specify any rules. In `v19.x`, this security group has been removed due to the predominant lack of usage (most users rely on the the shared node security group). While still using version `v18.x` of your module definition, remove this security group from your node groups by setting `create_security_group = false`.
