Why does `fs.writeFile` give “EBADF: bad file descriptor” when using `./`, but works with `/` in Node.js 22.14.0?

I’m encountering an issue with Node.js fs.writeFile when trying to write to a file using a relative path (./message.txt). Whenever I use ./, I get the error:

[Error: EBADF: bad file descriptor, write] {
  errno: -4083,
  code: 'EBADF',
  syscall: 'write'
}

However, if I use /message.txt, the file gets created in the root of my C drive (C:message.txt) without any issues. I’m using Node.js v22.14.0, and this problem persists even after ensuring the directory exists and using absolute paths. I suspect it could be related to Node.js handling of relative paths in this version. Has anyone else experienced this, or is there a workaround to reliably write files using a relative path?

What I Tried & Expected Behavior

1. Reinstalling Node.js – Issue persists in v22.14.0.
2. Using an absolute path (C:/Users/niran/Documents/message.txt) – Works fine.
3. Using path.join(__dirname, "message.txt") – Still throws EBADF error.
4. Ensuring the directory exists before writing – No change.
5. Running the script as an administrator – No effect.

Here’s my latest attempt:

try {
  const fs = require("fs");
  const path = require("path");

  const filePath = path.join(__dirname, "message.txt");

  console.log(filePath);

  fs.readFile(filePath, "utf8", (err, data) => {
    if (err) {
      console.error(err);
      return;
    }
    console.log(data);
  });

  fs.writeFile(filePath, "Hello, Node.js", (err) => {
    if (err) {
      console.error(err);
      return;
    }
    console.log("The file has been saved!");
  });
} catch (error) {
  console.log(error);
}

What I Expected

I expected the file to be created in the same directory as my script, but instead, it throws EBADF.
