Thank you for the detailed report and the diagnostics bundle. This error indicates that the generation was terminated by the provider (chatgpt-codex) with a PROVIDER_ERROR after approximately 1 minute 41 seconds (100885 ms). The model in use is gpt-5.4, which is a very recent model variant.

From the logs:

[2026-05-06 18:23:01.161] [error]  (main:ipc) [generate] step=send_request.fail {
  provider: 'chatgpt-codex',
  modelId: 'gpt-5.4',
  ms: 100885,
  stopReason: 'error'
}

The terminated message often occurs when:

• The provider closes the connection unexpectedly (timeout, rate limit, or model unavailability).
• The request is cancelled by the user or the app.
• The model ID gpt-5.4 is not yet whitelisted or fully supported by the chatgpt-codex provider adapter.

Next steps to help us diagnose:

1. Which model variant was selected? In the model selector, did you choose gpt-5.4 explicitly, or was it auto-detected? (The chatgpt-codex provider dynamically lists available models from the API.)
2. Did the generation complete? Was there any visible progress (tool calls, partial text) before the error appeared? The logs show tool calls up to seq 55, then the error at seq 56, which suggests the agent finished a turn but the final send_request failed.
3. Can you reproduce with a different model? Try with gpt-4o or gpt-4.1 (if available) to see if the issue is specific to gpt-5.4.
4. Network / timeout: Is your internet connection stable? The 100-second duration is slightly above typical generation times – could be a slow response or a provider-side timeout.

Relevant code paths (for maintainers):

• Provider adapter for chatgpt-codex lives in packages/providers/ (likely src/providers/chatgpt-codex.ts).
• The error PROVIDER_ERROR is normalized in packages/core/src/generate.ts via NormalizedProviderError.
• IPC handler codesign:v1:generate is in apps/desktop/src/main/ipc/generate.ts.

If you can share the redacted content of the diagnostics bundle (specifically the chat-messages and provider logs) that might help pinpoint the exact provider response.

Thanks again for reporting – this helps us improve provider compatibility with newer models!
