AWS CLI Denied Permission Due to IAM Policy - Policy has all permissions correct. Previously worked fine.

I had to update my CLI on a few devices, and I am now unable to access anything pertaining to gamelift's API via an explicit denial. I double checked the permission policy that I assigned to the IAM user, and while it is set to allow full access to resources, it will not work.

Any suggestions or recommendations? I have also tried re-creating the policy via JSON and the visual GUI. I even tried creating a new user to use, and nothing works. I even ended up uninstalling the CLI tool and deleting the configuration and credential files multiple times trying to see if that would fix the issue.

Policy below:

{ "Version": "2012-10-17", "Statement": { "Effect": "Allow", "Action": "gamelift:", "Resource": "" } }
