This is happening to me too since 7th September with Antigravity-IDE.
I tried Antigravity-x64 and it worked.
I downloading it from Google Antigravity - Download (direct link: storage.googleapis.), and unzipped it to ../Downloads/antigravity/Antigravity-x64.
Then I executed in the terminal of my Antigravity-IDE (after granting the file exec permissions):
`“$HOME/Downloads/antigravity/Antigravity-x64/antigravity”`
and the Agent Manager opened.
Now I work with both Antigravity IDE and the Agent Manager:
It seems Antigravity IDE and Antigravity-x64 use different endpoints to the servers.
I hope this gets fixed soon but at least it’s working right now until the solution comes.
