Randomly got 50L in your account, what business would you start

I’m 24, Software Engineer, have done many random gigs around, assume I got 50L in my account and want to start something (maybe franchise/airbnb anything) to have a decent passive income, side business. I don’t have any debt or anything of similar sort and can take decent risks (don’t want to invest in stocks, can do that later) What would y’all advise?
