Windows Codex app stuck on loading screen after first launch; app:// dynamic import fails

What version of the Codex App are you using (From “About Codex” dialog)?

26.616.51431

What subscription do you have?

pro 5X

What platform is your computer?

windows

What issue are you seeing?

After reboot, the first launch usually opens normally.
Subsequent launches often stay on the white Codex
loading screen, or show “糟糕，出错了”. Clearing cache/
profile, Reset-AppxPackage, winget repair, uninstall/
reinstall did not fix it.

What steps can reproduce the bug?

chrome_debug.log repeatedly shows:
Uncaught TypeError: Failed to fetch dynamically
imported module: app://-/assets/app-main-xvmdI65o.js

Also observed failures for:
app://-/assets/home-announcements-fWVpVpQ4.js

The asset exists in the installed package. If the
renderer is restarted after the failure settles, the
app loads successfully, suggesting a Windows/Electron
app:// packaged resource loading or renderer
initialization race.

What is the expected behavior?
