Bug type

Regression (worked before, now fails)

Summary

The OpenClaw Mac app crashes with SIGABRT every time the wake word is detected. Swift exclusivity access violation in VoiceWakeOverlayController.present().

Steps to reproduce

1. Run OpenClaw 2026.3.2 on macOS 26.2 ARM64
2. Enable Voice Wake in settings
3. Speak the configured wake word
4. App crashes immediately with SIGABRT (Abort trap: 6)

Expected behavior

Voice overlay appears and wake-word session begins normally without crashing.

Actual behavior

App crashes with SIGABRT immediately. Swift exclusivity violation: two async tasks race on VoiceWakeOverlayController.present() triggered from VoiceWakeRuntime.triggerOnlyPauseCheck.

OpenClaw version

2026.3.2 (build 2026030290)

Operating system

macOS 26.2 (25C56) ARM64 - Mac mini (Mac16,10)

Logs, screenshots, and evidence

Impact and severity

Affected: All macOS users with Voice Wake enabled on macOS 26.2
Severity: High - completely blocks voice wake feature
Frequency: 100% reproducible on every wake-word trigger
Consequence: App crashes, voice wake unusable. Push-to-Talk (Cmd+Fn) works as a workaround.

Additional information

Key crash stack:
swift_beginAccess > VoiceWakeOverlayController.present() > VoiceWakeRuntime.beginCapture > VoiceWakeRuntime.triggerOnlyPauseCheck

Incident ID: C3A0CAEB-B35E-493A-A670-6E2D450F9552
Workaround: Disable Voice Wake, use Push-to-Talk (Cmd+Fn) - different code path, no crash.
