Three years ago I made a paper wallet using an online generator and my public key is 1MXb3vY5sCC2rB2bD2rusQjxEyYUDEKcHT. I stored my private keys locked in a Keepass password manager (with a very long and strong password) and made sure it's different than my primary general Bitwarden password generator. I just checked my balance 2 days ago and realized it's all missing since 11/25/2022. Any advice how to get my money back?  I feel like reporting or even trying to sue Sarkis Sarkissian (new owner of the bitcoinpaperwallet) would cost me even more headaches and waste of time since not guaranteed that I will get my money back. Do you happen to know any success stories or any recommendations on what I should do?

Thanks in advance.
