Fix NotFoundError

✅ Solution

The "NotFoundError" in Qwik often indicates that `insertBefore` or similar DOM manipulation methods are being used with a reference node that's no longer a child of the intended parent. This usually happens due to asynchronous updates or conditional rendering that alters the DOM structure before the insertion occurs. To fix this, ensure that the target parent and reference node are actively present as children when you call `insertBefore`; defer the insertion operation until after the parent and reference node are initialized and available, often by using Qwik's lifecycle hooks or reactive updates to synchronize DOM operations.
