Hello user4137,

Welcome to the forums!

Diagnosis:

It appears your installation is suffering from a permissions mismatch and a corrupted file structure. The logs indicate updates are disabled due to running as Admin, which breaks the OAuth token handoff from your browser to the IDE. Additionally, core UI files (cascade-panel.html) are missing from the installation directory.

Recommended Fix:

You need to perform a “Clean Reinstall” to reset the permissions.

Uninstall Antigravity: Remove the application via Windows Settings.

Clear Local Data:

Navigate to C:\Users\Jiaqi\

Delete the .antigravity folder entirely. (This removes the cached extensions and corrupted config).

Optional: Check %APPDATA% (usually C:\Users\Jiaqi\AppData\Roaming) and delete any Antigravity folders there as well.

Reinstall (Crucial Step):

Run the installer normally (double-click). Do not right-click and select “Run as Administrator.”

If the installer asks, install for “Just Me” (User) rather than “All Users” if the option is presented.

Launch:

Open Antigravity normally (again, do not run as Admin).

Attempt the Sign-In process again.

Captain’s Log Supplemental:

The warnings about API proposal … DOES NOT EXIST are red herrings (noise) related to VS Code versioning and can be ignored. Focus entirely on the Admin privileges and the missing HTML file.

Hope this helps and good , if not I’ll do a follow up of needed info. I left my Captains logs to show you the issue in focus as the primary cause most likely.

~Cmd.Proton🖖

user4137 · December 27, 2025, 7:33am

Hi Proton，

Thanks for your reply! As your suggestions, I did:

Uninstall Antigravity by unins000.exe
Remove ~/.antigravity and the file Antigravity Dir in %AppData%\Roaming\
Reinstall Antigravity.exe (b1618872ed5b166170318cc3d44ab745) by all default options with User role, yes, double clicks.
Double-click to start (with User role) and proceed to try to sign in.
However, the problem persists as before.
FYI, I paste the log again:

Clicking on the “Sign in with Google” button is also unresponsive, also on the win11 system
