Amazon EC2 cluster error Unable to provide ec2 instances because "requested EMR_EC2_DefaultRole instance profile is not valid"

Question

I am trying to create a cluster using the amazon aws console with the default role. A cluster is created and it remains in a start state sometimes, and then ends with this error: Failed to provide ec2 instances because "Invalid profile of requested instance EMR_EC2_DefaultRole"

I tried editing the default user trusts, but again it says it is not allowed. In addition, I registered as a root account.
