Error when launching AWS CloudShell: "Unable to start the environment"

Question

* I'm getting an error when trying to launch AWS CloudShell in the `us-west-2 (Oregon)` region.
* My IAM Role has Administrator Access, and I'm the only creator/user of the AWS account. 
* I enabled AWS Organizations, but am not using any features of it right now.
* I am not using any permissions boundaries in IAM
* I am **not** receiving any kind of "access denied" error message. It is just a generic, useless message (see below).

Any ideas on how to resolve this?

`Unable to start the environment. To retry, refresh the browser or restart by selecting Actions, Restart AWS CloudShell.`

Answer

Can someone please look into this? I have tried all the suggestions with no luck. The negative rating on the answers indicates that no good solution exist for this issue. I am facing this issue in ap-southeast-2.

Unable to start the environment. You must verify your account before accessing CloudShell. To verify your account, contact AWS Support .
The link goes to https://support.console.aws.amazon.com/support/home with no guidance as to how to "verify" my account.

Answer

Hi, good question.

A couple things I would start with:

* What region are you in?  Cloudshell only operates in the following regions: https://docs.aws.amazon.com/general/latest/gr/cloudshell.html
* Are there any other policies that could be denying CloudShell?  SCP (Organization Level), Managed Policies, Permission Boundaries?  If not, Admin Access should do the trick (Cloudshell:*).
* Have you restarted?  Actions -> Restart CloudShell.  This will kill any active sessions you have.
