`copilot --continue` exit code 1 when changing model

[doggy8088]

Describe the bug

I hope changing the model won’t break Copilot on the next launch. Currently, it exits with code 1.

Affected version

GitHub Copilot CLI 1.0.18.

Steps to reproduce the behavior

1. Run copilot
2. Enter hi
3. exit copilot
4. change to another model by edit ~/.copilot/config.json or change model in the copilot.
5. Run copilot again.
6. You can't enter any prompt.

Expected behavior

I expected Copilot CLI should handle everything for me. It should load context from the last session even using different model.
