Hooks rendered conditionally (different count)
Rendered fewer hooks than expected|Rendered more hooks than expected
Fixes
- 1.Never place hooks inside if/else blocks, loops, or after early returns
- 2.Move conditional logic inside the hook, not around it
- 3.Ensure all hooks are called in the same order on every render
