What is the expected behavior?

Workarounds

Switch to another model → chat resumes immediately (context preserved).
Delete the failed conversation and retry → works.
Repro Frequency

Intermittent; only happens at newConversation start. Once a session is active, continuing or switching models is fine.
Additional Notes

All models can be listed and used outside of newConversation.
Happy to provide verbose logs if there’s a flag (e.g., --verbose, DEBUG=*).
If large workspaces during initialization are known to cause delays, I can try ignoring node_modules, .git, .astro, etc., and report back.
