Cannot stop or terminate EC2

When I checked the EC2 again, I found this issue resolved.

It sounds like your EC2 instance i-09a137b930abd32b9 is stuck in the "shutting-down" state due to an underlying issue on the AWS host server, which is indicated by the "Server.InternalError" message. When this happens, the instance can no longer respond to normal API calls, and the only way to resolve it is to force the termination. The most reliable method to do this is by using the AWS Command Line Interface (CLI). You can issue the command aws ec2 terminate-instances --instance-ids i-09a137b930abd32b9 to forcefully terminate the instance. If you have already tried this or if the instance remains in the shutting-down state for an extended period after running the command, the final step is to contact AWS Support. You should open a technical support case with them, provide the instance ID, and explain the situation. They have the internal tools to manually resolve the instance's state and complete the termination on the backend.
