Summary

Investigate and fix sudden production app crash on macOS Intel (x86_64) where OpenHuman quits unexpectedly with EXC_CRASH (SIGABRT).

• App: OpenHuman production build
• Version shown in crash report: 0.53.4
• Process: OpenHuman

Screenshot Evidence

Crash report screenshot should be attached to this issue for debugging context.

Scope

• Collect and inspect full macOS Intel crash report for stack trace and loaded libraries.
• Correlate crash with app logs/Sentry release events for version 0.53.4.
• Compare Intel vs Apple Silicon behavior if possible.
• Check recent webview/CEF/browser changes that may be Intel-specific.
• Investigate whether crash is related to embedded Slack/webview usage, notifications, or CEF runtime.
• Add defensive handling/logging around suspected crash path.
• Verify fix on macOS Intel production-equivalent build.

Acceptance Criteria

• Root cause of Mac Intel SIGABRT crash is identified.
• Crash is fixed or mitigated for Intel builds.
• Sentry/crash reporting links the crash to version 0.53.4.
• App no longer quits unexpectedly under same reproduction flow on Mac Intel.
• Regression test or manual verification notes are added.
