    Try using a typescript version between >=3.3.1 <4.4.0.
    Here you have the list of typescript versions available.

    After changing the version, remove node_modules folder and package-lock.json file. Then execute npm install

    I wouldn’t downgrade my Typescript, as you will miss out on newer TS features – I would find a way to update @typescript-eslint/typescript-estree.

    You might not have this installed directly and this might be a dependancy of another package, @typescript-eslint/experimental-utils which is dependancy of @typescript-eslint/eslint-plugin for instance, so track down the parent package in your yarn.lock / package.lock file and bump it, as a result it should bump @typescript-eslint/typescript-estree too.

    I was struggling with the same warning. Solved it by updating eslint and related packages to the latest by running:

    npm i eslint@latest @typescript-eslint/parser@latest @typescript-eslint/eslint-plugin@latest --save

    Now, I have the following versions in my package.json and I am not receiving the warning anymore

    "eslint": "^8.38.0",
"eslint-config-google": "^0.14.0",
"eslint-plugin-import": "^2.22.0",
"typescript": "^5.0.4"
