'paths' disappeared in tsconfig when i run ‘npm start’

My project is init based on create-react-app，and i install ‘typescript’ in my project， then edit the config of ‘tsconfig.json’:

 "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "components/*": [
        "src/components/*"
      ]
    }
  },

when i run ‘npm start’, i got some problems, and one is, ‘paths’ disappeared。

i have got the correct solution，set ‘paths’ in a external files, then send this url to ‘extends’。

But, I am very confused， why did i have this problem??？？？？？？

@camillalo CRA allows using absolute paths out of the box. Even though you’ll be only able to use actual folder names, it does the job well. The docs: https://create-react-app.dev/docs/importing-a-component/#absolute-imports

{
  "compilerOptions": {
    "baseUrl": "src"
  },
  "include": ["src"]
}

Getting the same issue when trying to add "paths" : { ... } to my tsconfig.json.
