我有一个基于nextjs的ReactJS+Typescript网站，我的操作系统是windows 11。当我执行npm run dev时，我在终端中得到这样的输出：

PS C:\Users\hosap\Documents\Programming\NextJSApplication\next-typescript> npm run dev

> next-typescript@0.1.0 dev
> next dev

ready - started server on 0.0.0.0:3000, url: http://localhost:3000

字符串
消息显示已成功编译的客户端和服务器，但当我访问localhost:3000时，我的浏览器只显示
x1c 0d1x的数据
正如你在这里看到的，浏览器正在接收来自localhost：3000的404错误

该项目的工作，直到2天前，但现在它不工作，我所有的本地分支机构。我不确定我的最后一次改变是否搞砸了这个项目，但我在工作时没有遇到这样的问题。
npm run start也显示相同的404错误。是什么导致了这个问题？
我尝试的是：

1. npm ci
   1.重新启动计算机
   1.删除environment.d.ts中的空导出
   没有工作：（
