[fasttime]

Environment

Node version: v19.3.0
npm version: v9.2.0
Local ESLint version: v8.30.0 (Currently used)
Global ESLint version: Not found
Operating System: darwin 22.1.0

What parser are you using?

Default (Espree)

What did you do?

Configuration

{
    "parserOptions": {
        "ecmaVersion": "latest"
    },
    "rules": {
        "prefer-arrow-callback": [
            "error"
        ]
    }
}

test(
  function ()
  { }
);

What did you expect to happen?

Autofix should fix the code like this:

test(
  () =>
  { }
);

What actually happened?

Autofix produces unparseable code:

test(
  ()
  => { }
);

DEMO LINK

The problem occurs when the function body starts on a new line, like in the Allman style.
