Subject: Antigravity IDE Login Error - "Unexpected issue setting up your account
Hi Antigravity Support Team,
I am encountering an issue while trying to log into the Antigravity IDE. Every time I complete the authentication flow, the application shows an error screen stating: “There was an unexpected issue setting up your account.”
Here are a few details about my setup:
-
Antigravity 2.0 logs in and works completely fine without any issues.
-
The problem is strictly isolated to the Antigravity IDE application.
-
I have already tried reinstalling the application, clearing local cache files, and ensuring no conflicting background processes (language_server_windows_x64.exe) are blocking the token handoff, but the error persists.
Could you please help me resolve this account setup or token looping issue?
Thank you,
Rushikesh Padghankar
Hello there! So, from what I know, standard reinstalls actually leave behind cached app data and OAuth tokens, which is usually why this persistent error happens—especially since your Antigravity 2.0 access works fine.
Reinstalling the IDE binary doesn’t clear corrupted local session files. You need to manually purge them:
Windows: Fully close the IDE. Press Win + R, type %APPDATA%, and delete both the Antigravity and Antigravity IDE folders. Do the exact same thing in %LOCALAPPDATA%. It is indeed quite a chore…
It’s also worth mentioning that If you are using a Google Workspace, or work account, domain admins often allow web logins (which is why Antigravity 2.0 works) but block custom app developer/IDE scope grants.
Try signing into the IDE with a personal @gmail.com account, or another one brand new and see if it makes a difference.
Best of luck,
