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

App does not open so cannot determine the version(latest from microsoft store)

What subscription do you have?

Plus

What platform is your computer?

Windows 11 25H2 (Microsoft Windows NT 10.0.26200.0 x64)

What issue are you seeing?

Codex app when pulled in the front shows splash screen and the app UI is not accessible making it impossible to use the app.

Looking at above image, if we put the app in background i can see the app.

But as soon as i pull the app in foreground, the app UI changes to codex logo. See below image

I also encountered this. Microsoft Store says it's version is 26.422.8496.0.
