[Bug]: Group Chat with Customized Speaker Selection Method Does Not Complete Task

[DLWCMD]

Describe the bug

After adding a cell for !pip install and creating the OAI_CONFIG_LIST, I attempted to run the notebook. I was presented with a series of questions to answer which I answered pressing the enter key, the proposal from the planner seemed to remain unchange. At that point, I assumed I was to exit the chat. I have attached the result, which appears to be the Chat Result. I don't see any of the expected output in a readable output form.
Chat_Result.zip

I expected more, or did you not intend to provide formatted output?

Steps to reproduce

1. Add !pip install function
2. Create endpoint
3. Run workbook. At some point, I assume the user would exit the chat.
4. When that occurs, the Chat Result is displayed.

Model Used

gpt-4", gpt-4-1106-preview as selected by the filter

config_list = autogen.config_list_from_json(
    "OAI_CONFIG_LIST",
    filter_dict={
        "model": ["gpt-4", "gpt-4-1106-preview"],
    },
)

Expected Behavior

Formatted output of the task result, unless you did not mean to present.

Screenshots and logs

No response

Additional Information

Python 3.12
Jupyter Notebook, but not in Colab
