Codex macOS desktop renderer crash loop in 149.0.7827.197

Summary

Codex Desktop on macOS is repeatedly crashing/reloading the renderer and returning to the home page. Restarting the app does not resolve it.

Environment

• App: Codex macOS desktop
• Version observed in process args: 149.0.7827.197
• Architecture: arm64
• Date observed: 2026-07-01 through 2026-07-02

User-visible behavior

The Codex app briefly appears to restart/reload, then exits back to the home page. This has happened repeatedly, including after restarting the app.

Evidence

Crashpad sidecar records in Application Support/Codex/Crashpad/pending are being created repeatedly. Recent timestamps after clearing/restarting include:

2026-07-02 11:09:54
2026-07-02 11:11:32
2026-07-02 11:13:08

Latest sidecar content shows:

{"osarch":"arm64","ptype":"renderer"}

Earlier records appeared every ~1-2 minutes during the same session, all consistent with ptype: renderer.

Mitigations tried

• Restarted Codex app: issue continued.
• Stopped accumulated Computer Use / node_repl helper processes: issue continued.
• Moved GPUCache and Crashpad pending aside to reset renderer/cache state: issue continued.
• After cache reset, a new renderer crash appeared at 2026-07-02 11:09:54.

Related observation

Computer Use helper processes appear to grow in repeated groups after these renderer reloads, for example:

• SkyComputerUseClient mcp
• cua_node/bin/node_repl

Stopping these helpers reduces process accumulation temporarily, but the renderer crash loop still continues.

Expected behavior

The renderer should remain stable and the app should not reload/return to the home page repeatedly.

Notes

Local paths/usernames have been intentionally redacted from this report. A local diagnostic text report with process snapshots and Crashpad timestamps is available if maintainers need more detail.
