TypeScript language server fails to recognize new files and needs restart

Type: Bug

Since the last update(s) or so, the TypeScript language server fails to recognize or do any code completion on newly created (or copy-pasted) files, no matter if they are TS or TSX.

With TS files it fails to do code completion for any other code from my project (cannot find anything from my project to import when I do CTRL+SPACE).

For TSX files, it fails to recognize React and all I get is syntax errors for JSX code.

I have to manually restart the TS language server in order to fix this. That or wait ~5s.

Context:

• I am on the latest TS version 5.5.4
• I am working on a typical NextJS (14.2.5) project with shadcn-ui components.
  tsconfig is the nextj's default:

{
  "compilerOptions": {
    "lib": ["dom", "dom.iterable", "esnext"],
    "allowJs": true,
    "skipLibCheck": true,
    "strict": true,
    "noEmit": true,
    "esModuleInterop": true,
    "module": "esnext",
    "target": "ES2020",
    "moduleResolution": "bundler",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "jsx": "preserve",
    "incremental": true,
    "plugins": [

        "name": "next"
      }
    ],
    "paths": {
      "@/*": ["./*"]
    }
  },
  "include": ["next-env.d.ts", "**/*.ts", "**/*.tsx", ".next/types/**/*.ts"],
  "exclude": ["node_modules", ".next"]
}

Reproduce el problema en la configuración del proyecto Next.js indicada creando o copiando archivos TS y TSX nuevos; después, prueba la finalización y el reconocimiento de React antes y después de reiniciar el servidor de lenguaje de TypeScript. Traza el manejo de los archivos recién creados por parte del servidor de lenguaje; se considera terminado cuando los imports del proyecto, React y JSX se reconocen sin un reinicio manual ni una demora inexplicable.
