Cluster creation failure due to "You are not allowed to pass the role..."

Simply following another exercise, where due to the age of the presentation the materials are out of date. During cluster creation I get the following error: You are not allowed to pass the role arn:aws:iam::...:role/eksctl-corp-eks-cluster-cluster-ServiceRole-AHXkuur5AWUm (Service: Eks, Status Code: 400, Request ID: ...)" (RequestToken: ..., HandlerErrorCode: InvalidRequest

After much search and many hours on AWS service, costing me pretty pennies, I can only find a similar "solution" at: https://repost.aws/questions/QUoj76LPndQdi8LAKQV37BMw/couldn-t-able-to-create-eks-cluster-due-to-the-following-error-you-are-not-allowed-to-pass-the-role-arn-aws-iam-401231317770-role-eksclusterrole.

However, trying to follow the above solution I can not create a proper user. The manifest file for creating the cluster:

$ cat corp-eks-cluster.yaml
