Describe the Issue

Environment:

OS: Windows 11
Version: 10.0.26200.8457
Architecture: x64
Postman Version: 12.11.4
Installation Type: EXE installer
CPU/GPU: (fill your hardware here if needed)

Issue:
Postman desktop app launches from CLI but no UI/window ever appears. The application immediately crashes during Electron/Chromium GPU initialization.

Observed behavior:

No Postman window appears
Process starts briefly then exits
GPU process repeatedly crashes
Desktop Agent works correctly
Web version works
Only desktop renderer/UI crashes

Exact logs:

Additional observation:
Even when GPU disabling flags are passed, Postman logs:

The disableGPU setting is set to undefined
Not disabling GPU

Commands tested:

set ELECTRON_DISABLE_GPU=1 && "%LocalAppData%\Postman\app-12.11.4\Postman.exe"
"%LocalAppData%\Postman\app-12.11.4\Postman.exe" --disable-gpu
"%LocalAppData%\Postman\app-12.11.4\Postman.exe" --disable-gpu --disable-software-rasterizer
"%LocalAppData%\Postman\app-12.11.4\Postman.exe" --disable-gpu --use-angle=swiftshader

Troubleshooting already attempted:

Complete uninstall/reinstall
Deleted:
%LocalAppData%\Postman
%AppData%\Postman
Rebooted system
Reinstalled Desktop Agent
Firewall cleanup/re-allow
Disabled GPU flags
Swiftshader fallback
MPO disable registry fix:
reg add "HKLM\SOFTWARE\Microsoft\Windows\Dwm" /v OverlayTestMode /t REG_DWORD /d 5 /f
Reboot after registry modification
Clean profile launch
Compatibility mode
Running as Administrator

Expected behavior:
Postman desktop UI should launch normally.

Actual behavior:
Application crashes before renderer/UI appears due to repeated GPU process failures.

Notes:
This may be related to:

Electron/Chromium GPU initialization
Windows 11 Insider/newer builds (26200 series)
GPU driver compatibility
GPU disable flags not being honored internally

Steps To Reproduce

Steps To Reproduce

1. Install Postman Desktop App v12.11.4 on Windows 11 build 10.0.26200.8457 (x64)

2. Launch Postman normally from:

   • Start Menu
     OR
   • Command Prompt

Example:

"%LocalAppData%\Postman\app-12.11.4\Postman.exe"

3. Observe:

   • No UI/window appears
   • Process starts briefly and exits

4. Launch again from terminal with GPU disabling flags:

"%LocalAppData%\Postman\app-12.11.4\Postman.exe" --disable-gpu

OR:

"%LocalAppData%\Postman\app-12.11.4\Postman.exe" --disable-gpu --use-angle=swiftshader

5. Observe repeated GPU process crashes in console logs:

GPU process exited unexpectedly: exit_code=-2147483645
GPU process isn't usable. Goodbye.

6. Even with GPU disabling flags/environment variables, logs still show:

The disableGPU setting is set to undefined
Not disabling GPU

Result:

• Postman desktop renderer/UI never appears
• Application exits after repeated GPU process failures

Expected Result:

• Postman desktop UI should launch normally
