react-dom.development.js:19055 Uncaught Error: A component suspended while responding to synchronous input. This will cause the UI to be replaced with a loading indicator. To fix, updates that suspend should be wrapped with startTransition.

原因

在使用懒加载组件时，可能还未加载完成，导致的不可预知的错误

解决

套一层Suspense组件

import React, { Suspense } from "react";

<Suspense>
    <LazyComponent />
</Suspense>
