insufficient permissions for the lab "IAM and EC2: Instance Profiles"

I am working on the lab "IAM and EC2: Instance Profiles" and in section 4 it requires launching an EC2 instance. The problem is that following all the steps, it returns the following error:

Instance launch failed
You are not authorized to perform this operation. User: arn:aws:iam::250176780079:user/aBCbsrMbk6Um5GQlxs7G is not authorized to perform: ec2:RunInstances on resource: arn:aws:ec2:us-east-1:250176780079:volume/* with an explicit deny in an identity-based policy.

Am I doing something wrong or is there actually a lack of permissions to complete it?

Thank you very much for your help.
