Antigravity PERMA KILLED in your PC. Even re-install wont FIX.

[Zhihong0321]

1. Chrome, Gemini, Antigravity combined tooked up 30GB cache in my C Drive.

2. ask Antigravity to move cache folder for all google product to my E: Drive.

3. Profile still stay in C: , only move E:

4. Antigravity give me a script to run in powershell.

5. move cache, and a script run after REBOOT PC

6. Chrome still work well.

7. But all Antigravity include agy CLI all = DEAD. PERMA DEAD

The Antigravity CLI automatically self-updates in the background.

======================

Then my antigravity, stop working, FULL UNINSTALL.

then when reinstall, even installation FAILED completely

the most problematic PIECE of software.

[Zhihong0321]

nevermind, fixed by Codex 5.5

the move cache script create by Gemini 3.5 Flash = Suicide.

Windows could not resolve the path correctly.

I replaced the broken self-referential junction with a real directory, then also fixed the same issue for these sibling cache dirs:

antigravity, antigravity-backup, antigravity-browser-profile, antigravity-ide, tmp

Verification passed:

agy --help now works.
agy no longer crashes immediately with the installation_id / log directory error.
No self-referential junctions remain under E:\cache\gemini.
