Research direction
No source file, test, or entry point is named. Start by reproducing the launch failure on Windows 11 ARM64 with the Microsoft Store build, then inspect the desktop-app startup path and Windows diagnostics, including the reported LiveKernelEvent 141. Done means the app remains open and usable on the affected Snapdragon X Plus environment without regressing normal launches.

Additional information
Environment:
- ASUS Vivobook S15 S5507QA
- Windows 11 Home 24H2
- ARM64
- Snapdragon X Plus
- Qualcomm Adreno X1-45 GPU
Additional notes:
- Microsoft Store version: 26.707.9981.0
- Codex CLI works normally.
- Codex Desktop App always exits immediately after launch.
- Cursor works normally.
- Chrome works normally.
- Reinstalling the app does not resolve the issue.
- No Application Error is logged.
- Windows reports LiveKernelEvent 141.
This appears to be specific to Windows on ARM64 (Snapdragon X Plus), because the Codex CLI works normally while only the Desktop App crashes immediately.
