Q Fails to continue after generating Python Graphs

### 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 15.5.0 (24F74)

### Expected behaviour

Once Q generates the Python Graphs to continue the conversation.

### Actual behaviour

Q will generate graphing in Python based on chat requests and then fail to continue the conversation. It becomes unresponsive to all further prompts. I am unable to run Q doctor because of this. This has happened a few times now in different discussions.

### Steps to reproduce

Provide data via CSV and request Q to generate a visual.
