Solution to Fix

1. Manually deletion is recommended in this case.

2. List your roles and then apply delete to the instance profiles.

   $ aws iam list-roles
   $ aws --region=<region-name> iam delete-instance-profile --instance-profile-name <profile_name>
   

Example Given Below

    $ aws --region=us-east-1 iam delete-instance-profile --instance-profile-name  ocp4-925gm-master-profile

    $ aws --region=us-east-1 iam delete-instance-profile --instance-profile-name  ocp4-925gm-worker-profile
