Cloudshell wont start

Question

Full Error:  
  
Unable to start the environment. To retry, refresh the browser or restart by selecting Actions, Restart AWS CloudShell.  
  
I have this permission attached to my IAM user. AWSCloudShellFullAccess. Here its JSON description:  
  
{  
    "Version": "2012-10-17",  
    "Statement": \[  
        {  
            "Action": \[  
                "cloudshell:*"  
            ],  
            "Effect": "Allow",  
            "Resource": "*"  
        }  
    ]  
}  
  
I tried to follow the 'Troubleshooting AWS CloudShell' guide. Nothing works. That generic error doesnt say anything. Please help.

I'm getting a similar error. Changing browsers, regions or switching to root account does not change anything. Any hint on where to look at?
