Loss of journal and indents

Being using logseq since beginning of the year. Data on local folder. I update to latest version today. It say so to “download graph”, markdown syntax change ("-") and beta version. The download graph didn’t complete for me. And then opening Brave browser again, it says local filesystem not supported. It was before. So I open my folder in Chrome private mode (cuz regular has same local filesystem not supported message), my April and May journals are missing. Actual files (journal/*.md) also. And pages where there are multiple level of indent are all flattened.

Is there something I can do to recover the loss? Thanks!

Edit: I’m using the web version. I visited logseq.com to update.
