Describe a challenging bug you fixed in a previous project. What was your debugging process, and how did you eventually resolve it?

I encountered a significant bug related to state management in a React application. To debug, I first replicated the issue in a controlled environment. I utilized console logging and React Developer Tools to trace state changes and component re-renders. After identifying an asynchronous state update issue, I revised the state management logic using hooks. The issue was resolved, and I implemented additional tests to prevent future regressions.
