Windows app: Antigravity shows a generic icon in the "Open in" menu

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

26.325.3894.0

What subscription do you have?

Unknown

What platform is your computer?

Microsoft Windows NT 10.0.26100.0 x64

What issue are you seeing?

In the Windows desktop app, Antigravity appears in the "Open in" menu, but its icon is rendered as a generic gray/default icon instead of the Antigravity app icon.

I verified locally that:

• Antigravity.exe itself has the correct app icon.
• Recreating the Windows Start Menu shortcut did not change the icon shown in Codex.
• Codex's bundled apps/antigravity.png asset is correct.

This looks specific to Codex Desktop's Windows "Open in" app/icon resolution, not to the Antigravity installation itself.

What steps can reproduce the bug?

1. Install Antigravity on Windows.
2. Open Codex Desktop.
3. Open any workspace/thread that shows the "Open in" menu.
4. Open the "Open in" menu.
5. Observe that Antigravity is listed with a generic icon instead of its real app icon.

What is the expected behavior?

Antigravity should display its real application icon in the "Open in" menu.

Additional information

Local Antigravity install path on this machine:
C:\Users\jianzhangg\AppData\Local\Programs\Antigravity\Antigravity.exe

Codex package observed here:
OpenAI.Codex_26.325.3894.0_x64__2p2nqsd0c76g0

This appears similar in symptom to #16002 (Wrong icon for Jetbrains IDEs), but for Antigravity.
