Reset RAG index every time restart obsidian

[Enmani]

Greetings,
I've met a new problem. every time I close and open my obsidian, I found that my RAG data disappeared (reset as early version)
I've rebuilt it several times (using local Ollama), still lost it every time. Any clues about that?

Appreciate for any feedback :)
