Comment (by ermiuyo):

 Replying to [comment:2 ermiuyo]:
 > 1. The component tree has changed, but React still holds references to
 old nodes.
 > 2. A missing or incorrect key in a list causes React to misidentify
 elements.
 > 3. Conditional rendering removes elements unpredictably.
 > 4. Directly manipulating the DOM instead of relying on React’s virtual
 DOM.
 Make sure the parent component exists before inserting a child element. If
 using refs, validate them before modifying the DOM.


 {{{
 useEffect(() => {
   if (parentRef.current) {
     // Safe operations
   }
 }, []);
