Bug: Whenever my macOS goes to sleep for a while and then wakes up, amazon-q will fail.

### Checks

- [x] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue
- [x] I have run `q doctor` in the affected terminal session
- [x] I have run `q restart` and replicated the issue again

### Operating system

macOS

### Expected behaviour

amazon-q provides auto-complete function normally

### Actual behaviour

Whenever my macOS goes to sleep for a while and then wakes up, amazon-q will fail. It will not show auto-complete suggestions, and I have set `system` in the theme. When I am in a light theme, the color of the Amazon Q dashboard is still dark. I have to restart it manually, and Amazon Q will show auto-complete suggestions again, and the theme will be updated accordingly.

### Steps to reproduce

Let your macOS sleep for a while and then wake it up.
