Failed Startup, Same Idea: Is It Worth Trying Again?

Suppose you failed your startup challenge with business item A (your company went bankrupt), would you try again with the same business idea A? I previously ran an HR SaaS startup and the company went bankrupt. It's been a year since then, and my passion for it hasn't waned. Based on the things I learned and the feedback I received while running the business, I'm thinking of trying the 'same business item' in a different way. But would this be a foolish move, 'repeating the same mistakes'?
