Brave randomly logged out of all sessions and cant decrypt passwords anymore

The brave Browser deleted all my Data. I didn’t do an Update or delete any data myself, I just closed brave and reopened it. Suddenly i was logged out of every Email Account and all my saved Passwords were deleted as well. Also my brave was back in bright mode. The only thing it kept are my browser history and my bookmarks.
The only thing bothering me about this is my saved passwords.
I looked in the App data and found a login file. I am fairly certain that this contains my saved passwords, since i recognize most of the links. (i can only read the links, not the passwords) Somehow The Browser doesn’t recognize it though. (Im on windows btw) I haven’t changed any settings on my PC nor does anyone else have access to it. Is there any way to make brave recognize the decripted “login file”?
