Antigravity Version: Latest
Description: I am encountering a persistent and critical login issue. My initial account ran out of quota, so I purchased a Pro subscription on a new account. However, when I attempted to log in with the new Pro account, the application became completely unresponsive. The login process hangs, and the logs indicate that the auth provider is failing to sync the state.

Steps Already Attempted (Without Success): To resolve this, I performed a completely clean wipe of the application and its hidden cache directories by executing the following commands in the terminal:
Bash
rm -rf ~/.antigravity
rm -rf ~/Library/Application\ Support/Antigravity
rm -rf ~/Library/Caches/Antigravity
After executing these commands, I completely uninstalled and reinstalled the latest version of Antigravity. Despite this clean installation, the exact same key not found error persists when I try to log in.
It appears the auth state is permanently stuck or failing to generate/store a new token for the switched account. Any help would be greatly appreciated as I am currently locked out of my Pro subscription.
