Codex process errored: ...exited unexpectedly (code=unknown, signal=SIGTRAP) / thread_tools

OpenAI Developer Community July 3, 2026
Source

Installed Codex app (Intel version)

VS code gives:

Codex process errored: Codex app-server process exited unexpectedly (code=unknown, signal=SIGTRAP). Last CLI error: codex_core_plugins::manifest: ignoring interface.defaultPrompt: maximum of 3 prompts is supported path=/Users/somebody/.cache/codex-runtimes/codex-primary-runtime/plugins/openai-primary-runtime/plugins/template-creator/.codex-plugin/plugin.json codex_core_plugins::manifest: ignoring interface.defaultPrompt: maximum of 3 prompts is supported path=/Users/somebody/.cache/codex-runtimes/codex-primary-runtime/plugins/openai-primary-runtime/plugins/template-creator/.codex-plugin/plugin.json

Insider gives:

Codex process errored: Codex process is not available

codex_core_plugins::manifest: ignoring interface.defaultPrompt: maximum of 3 prompts is supported path=/Users/somebody/.cache/codex-runtimes/codex-primary-runtime/plugins/openai-primary-runtime/plugins/template-creator/.codex-plugin/plugin.json

I’ll just use the older version for now.
