See https://serverfault.com/questions/872046/aws-windows-ec2-instance-does-not-recognize-assigned-iam-role. I had to set the Availability Zone and the Subnet of Windows workers to the same as those used for creating the AMI.
Fixed in https://github.com/dmlc/xgboost/pull/8142. As long as we use EC2 Image Builder service, we don't have this problem.
