Desktop app renderer crashes on launch (render-process-gone, exit code -2147483645 / STATUS_BREAKPOINT) on Windows 11 24H2

Summary

Command Code Desktop (v0.1.35) will not open on Windows 11 24H2. The Electron main process starts fine and creates the window, but the sandboxed renderer process crashes immediately on every launch, so the window never becomes usable. The app looks like it is starting and then shows nothing.

Expected Behavior

The desktop app opens and shows a usable main window.

Actual Behavior

The main process starts and logs main.window-created and main.harness-loaded, then the renderer dies. The window never becomes usable.

%APPDATA%\Command Code\logs\main.log:

[2026-09-19 16:52:57.273] [info] Command Code starting - v0.1.35 (packaged: true)

[2026-09-19 16:52:57.835] [error] [render-process-gone] crashed -2147483645

Exit code -2147483645 is 0x80000003 (STATUS_BREAKPOINT). Two render-process-gone events are logged per launch.

Steps to reproduce the issue

1. Install Command Code Desktop 0.1.35 (x64) on Windows 11 Pro 24H2 (build 26100), Intel Core i3-4150.
2. Launch the app from the Start Menu or Desktop shortcut.
3. Watch %APPDATA%\Command Code\logs\main.log - the window is created, then render-process-gone (crashed -2147483645) is logged twice.
4. The window never becomes usable.

Consider handling the case where the Windows renderer sandbox cannot initialize, instead of the renderer crashing with STATUS_BREAKPOINT. In resources/app/out/main/index.js the window is created with webPreferences.sandbox = true unconditionally; a fallback (or a documented opt-out) would let the app start on affected machines.

Additional context

Narrowed down on this machine:

• Not corrupted user data: launching with a fresh --user-data-dir crashes identically.
• Not GPU/driver: launching with --disable-gpu still crashes.
• Not forced ASLR/CFG: Windows Exploit Protection is at defaults (ForceRelocateImages NOTSET, CFG NOTSET), HVCI not running.
• Build is current: v0.1.35 is the latest desktop release.

Workaround that works: disabling the renderer sandbox. Both --no-sandbox and ELECTRON_DISABLE_SANDBOX=1 make the app start normally (reaches main.ready-to-show, zero crashes). The app hard-codes webPreferences.sandbox = true in resources/app/out/main/index.js.

Environment:

• Windows 11 Pro, build 26100 (24H2)
• CPU: Intel Core i3-4150 (Haswell, 2013) - not officially supported by Windows 11
• Command Code Desktop 0.1.35 (x64), Command Code CLI 1.58.0
• Windows Defender is the only AV product

Points to a Chromium renderer-sandbox incompatibility on this OS/CPU combination.

Iniziate in resources/app/out/main/index.js, dove webPreferences.sandbox è abilitato incondizionatamente, e analizzate la configurazione della finestra del renderer e la gestione di render-process-gone. Riproducete il problema su Windows 11 24H2, confrontando l’avvio normale con --no-sandbox o ELECTRON_DISABLE_SANDBOX=1. Il lavoro è completato quando l’app raggiunge una finestra utilizzabile senza arresti anomali del renderer, mantenendo una sandbox appropriata oppure documentando l’opt-out.
