Funds went missing without trace on activity please help

I was playing crypto drake ball and did a few attacks and then shut down my laptop. I have over $100 of BNB on my Binance Smart Chain Network. But when I opened my laptop after 3 hrs and check my game and metamask, my BNB was no longer there. I Checked my metamask activity and the last activity there was the attack I did before I shut down my computer. I need help in recovering my lost funds please help. Anybody has any idea about this please?
