### ROOT CAUSE
The issue occurs because `useRef` initializer functions are called only once during initial render. If the function depends on state or external variables (impure function), it captures their initial values, preventing updates when state changes. This leads to incorrect `null` checks during subsequent renders.
### CODE FIX
Avoid using initializer functions for state-dependent refs. Instead, initialize the ref to `null` and update it in the component body:
```jsx
function MyComponent() {
const ref = useRef(null); // Initialize to null
// Update the ref based on state
if (someCondition) {
ref.current = null;
} else {
ref.current = someValue;
}
return
{/* ... */}
;
}
```
