[Windows] Repeated ChatGPT.exe crashes with 0xc06d007f cause system-wide micro-freezes

Start by reproducing the crash with the current Windows desktop app, then inspect Windows Event Viewer under Windows Logs → Application for the paired Application Error 1000 and Windows Error Reporting 1001 events. Use the reported exception code and WER dump details to narrow the fault; done means the repeated ChatGPT.exe crashes and system-wide micro-freezes no longer occur.

Description

The new ChatGPT/Codex Windows desktop app repeatedly crashes in the background and causes brief system-wide micro-freezes. During each freeze, the mouse cursor and the entire Windows UI stutter.

Windows Event Viewer records a new Application Error 1000 followed by Windows Error Reporting 1001. WerFault.exe also becomes active and uses significant CPU while collecting the crash report.

The application may remain visible or recover automatically, but the crashes continue periodically.

Versions

• UI version: 26.707.91948
• Release date shown in the app: July 16, 2026
• AppX package: OpenAI.Codex_26.707.12708.0_x64__2p2nqsd0c76g0
• Previous installed package 26.707.9981.0 showed the same crash
• Windows 11, build 26100
• GPU: NVIDIA GeForce GTX 1080 Ti
• NVIDIA driver: 32.0.15.8253

Steps to reproduce

1. Install the current ChatGPT/Codex app from the Microsoft Store.
2. Launch the app and open Codex.
3. Use the application normally or leave it running.
4. After a short time, the whole Windows UI briefly freezes.
5. Open Event Viewer → Windows Logs → Application.
6. Observe new Application Error 1000 and Windows Error Reporting 1001 events for ChatGPT.exe.

The issue can occur several times within a few minutes.

Expected behavior

The desktop app should run without repeatedly crashing or causing system-wide UI freezes.

Actual behavior

The main ChatGPT.exe process repeatedly generates crash reports:

• Faulting application: ChatGPT.exe
• Faulting module: unknown
• Exception code: 0xc06d007f
• Fault offset: 0x00007ffeb12d1ada
• WER event type: MoAppCrash
• WER P2: praid:App
• WER P8: c06d007f
• WER P9: PCH_84
• Example report ID: 644fc2c0-d8e0-4fc1-8086-1a2eeafd1fba

Example crash times immediately after a clean reinstall:

• App profile created: 09:56:42
• First crash: 09:56:57
• Second crash: 09:58:36

Each crash starts Windows Error Reporting and coincides with a system-wide micro-freeze.

Troubleshooting already performed

• Completely uninstalled and reinstalled the app.
• Confirmed that the local AppX profile was recreated from scratch.
• The first crash occurred approximately 15 seconds after the clean profile was created.
• Reset/reinstallation did not resolve the issue.
• Checked loaded modules in all ChatGPT.exe processes: no non-system or third-party DLL injection was found.
• Bitdefender Anti-tracker and Ace Script extensions were discovered in the Chromium profile, but both were marked as disabled.
• GPU utilization was very low during the issue.
• CPU frequency remained at 99–100%; no thermal or power-plan throttling was detected.
• RAM, disk latency, GPU load, DPC latency, and interrupt time were normal.
• No WHEA, display-driver, disk, or USB hardware errors were recorded.

This appears to be a regression or Windows compatibility issue in the current desktop app rather than a hardware/resource problem.

Please investigate the repeated native 0xc06d007f crash and the resulting WER dump loop.
