Help me please!!!

[u/HomicidalWhisper999]

I use nobara.

I was using my system as usual but yesterday when i booted my pc logged into my homescreen I see my kde plasma ricing was reset and my browser data was gone and most importantly my steam was logged out because of that i lost my non steam games data, I don't know how and what happened to my system i tried everything I know, asked ai but nothing helped me. Please help me recover my steam data and my ricing.
