What issue are you seeing?

After an unexpected Windows shutdown, the Codex/ChatGPT desktop app became stuck in an endless startup/loading loop. The window opens but never finishes loading.

The ChatGPT web app works normally on the same computer and account.

Troubleshooting already attempted:

Fully terminated ChatGPT/Codex processes
Windows App Repair
Windows App Reset
Complete uninstall, reboot, and reinstall
wsreset.exe
Launched ChatGPT.exe --disable-gpu
Renamed/cleared the package LocalCache

None of these changed the behavior.

Windows Event Viewer records:

Application Hang — Event ID 1002

ChatGPT.exe version 151.0.7922.137 stopped interacting with Windows

Executable:
C:\Program Files\WindowsApps\OpenAI.Codex_26.814.5167.0_x64__2p2nqsd0c76g0\app\ChatGPT.exe

Package:
OpenAI.Codex_26.814.5167.0_x64__2p2nqsd0c76g0

Hang type:

The issue began immediately after an unexpected computer shutdown. The desktop app worked normally before that.

Start by reproducing the Windows startup/loading loop after an unexpected shutdown, using the reported app version and Event Viewer Application Hang 1002 details. Review the Windows package executable and the attempted --disable-gpu and LocalCache troubleshooting context; done means the desktop app finishes loading reliably after the failure scenario.
