My bookmarks disappeared from one of my profiles - EDITED

Description of the issue:
I opened my Brave “Profile 1” today, as I do everyday, and my bookmarks had disappeared. Before that, last time I opened Brave I got a message saying that Brave had closed unexpectedly, which I don’t think happened cause the PC turned off as always.

EDIT: everything else is gone as well: extentions, browsing history (up to november 10th 2021)…
How can this issue be reproduced?
I opened my browser and all bookmarks had disappeared.

Expected result:
All bookmarks are there, and I use bookmarks a lot, I had important sites saved and now they are gone. Bookmarks in other profiles are OK.

Brave Version( check About Brave):
Versión 1.33.106 Chromium: 96.0.4664.110 (Build oficial) (64 bits)
