Brave Resetting

Hello.
My brave browser wasn’t opening earlier so I restarted my computer. Upon restart when I opened Brave it is as though I have never used it before. 0 ads and trackers blocked etc.

I’m really annoyed by this as all my website preferences, saved passwords, bookmarks etc are gone. Is there any way to retrieve these things? I’ve only been using brave for about 6 weeks since I built a new PC but I’ve still lost enough information to be greatly inconvenienced. This has never happened me before with any previous web browser.

Please help if possible
