Kubernetes version update fails

I'm updating a Kubernetes cluster from version 1.17 to 1.18 by using kOps (v1.18) with the command kops update cluster --yes

Just before the end of update operation update fails with a message:

kops update cluster command informs:

Will modify resources:
  AutoscalingGroup/master-eu-central-1b.masters.cluster.my_domain.org
        TargetGroups             [name:master-eu-central-1b.masters.cluster.my_domain.org-kube-ing-TG-1H011E1FCW114 id:arn:aws:elasticloadbalancing:eu-central-1:381749774323:targetgroup/kube-ing-TG-1H011E1FCW114/c4f3719c67327c8b] -> []

  AutoscalingGroup/nodes.cluster.my_domain.org
        TargetGroups             [name:nodes.cluster.my_domain.org
-kube-ing-TG-1H011E1FCW114 id:arn:aws:elasticloadbalancing:eu-central-1:381749774323:targetgroup/kube-ing-TG-1H011E1FCW114/c4f3719c67327c8b] -> []

Why update operation tries to delete those target groups and why it fails?

The previous update (1.16 to 1.17) was successful without any problems.
