What steps will reproduce the bug?

require('node:util').inspect(
  {
    get getString() {
      return 'foo';
    },
    string: 'foo',

    get getObject() {
      return { nested: true };
    },
    object: { nested: true },

    get getFunction() {
      return function fn() {};
    },
    function: function fn() {},
  },
  { getters: true },
);

How often does it reproduce? Is there a required condition?

It is perfectly reproducible.

What is the expected behavior? Why is that the expected behavior?

I expect functions to have similar rendering regardless of whether they come from a data property or a getter:

{
  getString: [Getter: 'foo'],
  string: 'foo',
  getObject: [Getter] { nested: true },
  object: { nested: true },
  getFunction: [Getter] [Function: fn],
  function: [Function: fn]
}

What do you see instead?

{
  getString: [Getter: 'foo'],
  string: 'foo',
  getObject: [Getter] { nested: true },
  object: { nested: true },
  getFunction: [Getter: <Inspection threw (TypeError: Symbol.prototype.toString requires that 'this' be a Symbol
