Bug: Login stuck with "state syncing error: key not found" after switching to a new account (macOS)

i’ve never heard of this before must be new

spoiller : i solved this 7 days ago, it looks like google is doing security sweeps every 12 hours now midnight and noon looking for multi account. theres only one solution - single google in mac settings accounts, single google in antigravity, single google in default system browser. make it all match, then reboot before it slaps ya with another 7 day.
