My all the settings are reset automatically

Now I just opened brave but all the settings are just reset automatically. I mean I am totally logged out of brave. When I completed the process of sign in all my settings were reset. I had to change all the settings as my previous one and then it got alright. But now the problem is that all the things are gone which I saved in brave meaning my passwords are all gone and I don’t remember them that’s why I used to save them. Is there any process that I can recover my passwords? and moreover the brave stats shown on new tab page is also reset and is showing zero however it was around 160k ads and trackers blocked before. Please see if there any way to recover all the things. This is a serious issue and I had many websites passwords saved and I can’t access them now and I am totally logged out from every site on brave.
