existsSync does not work on files containing a : on macOS

Version

23.10.0

Platform

macOS: 15.4.1 
Apple M2

Subsystem

fs

What steps will reproduce the bug?

1. In the Finder on Mac create a folder which contains a \ , e.g. "a\b"
2. In a terminal do an "ls", you will find "a:b" as the folder name
3. Now when using the fs package use the existsSync function
   Result: The folder is not found.

import * as fs from 'fs';
...
const folder = "a:b";
if (fs.existsSync(folder))
	console.log("found");
else
	console.log("not found");

Note: you have to use absolute paths according to where you create the folder:

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

Always

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

existsSync should find the folder.

What do you see instead?

I can't reproduce on M2/macOS 15.4:

$ mkdir 'a:b'
$ node -p 'fs.existsSync("a:b")'
true
