### Describe the bug

This is sort of an odd flow, but bear with me. In a flow such as `amplify import auth` there is a prompt where we can begin typing to filter the selection list. This works great, but there is a delay between selecting a value and the CLI proceeding (as if it were "loading"). During this delay if we backspace the prompt we can delete a few characters which will cause this error.

```
aws-amplify/reproductions/11174
➜ amplify import auth
Using service: Cognito, provided by: awscloudformation
✔ What type of auth resource do you want to import? · Cognito User Pool and Identity Pool
✔ Select the User Pool you want to import: · us-east-1_oIc5HauQus-east-1_ocHu0
🛑 Cannot read property 'value' of undefined

Resolution: Please report this issue at https://github.com/aws-amplify/amplify-cli/issues and include the project identifier from: 'amplify diagnose --send-report'
Learn more at: https://docs.amplify.aws/cli/project/troubleshooting/
```

### Expected behavior

- cli disables the input while loading
- cli shows indication it is loading/thinking/working in the background

### Reproduction steps

1. `amplify init -y`
2. `amplify import auth`
3. on the prompt to select your user pool, type a few characters to filter the list
4. make a selection
5. immediately after, hit backspace a few times
6. observe error

Research direction

Start with the `amplify import auth` command and the user-pool selection prompt, then reproduce the failure using the listed six steps on macOS with Node.js 18. Trace the prompt behavior after a selection while backspacing; done means the input is safely disabled or handled during loading, a loading indication is shown, and the reported error no longer occurs.
