Can't get it to work.

Installed via composer.
Literally copied your example code:

<?php
declare(strict_types=1);
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

require __DIR__ . '/vendor/autoload.php';

use YoutubeDl\Options;
use YoutubeDl\YoutubeDl;
$yt = new YoutubeDl();
$yt->setBinPath('C:\xampp\htdocs\youtube dl\yt-dlp');
$collection = $yt->download(
    Options::create()
        ->downloadPath(__DIR__.'\down')
        ->url('https://www.youtube.com/watch?v=oDAw7vW7H0c')
);
foreach ($collection->getVideos() as $video) {
    if ($video->getError() !== null) {
        echo "Error downloading video: {$video->getError()}.";
    } else {
        echo "test";
        echo $video->getTitle(); // Will return Phonebloks
        // $video->getFile(); // \SplFileInfo instance of downloaded file
    }
}

additionally only set php $yt->setBinPath('C:\xampp\htdocs\youtube dl\yt-dlp');. And added error reporting.
I'm getting no results. $collection is empty. Page is blank.

Set debugging to see what's going on:

$yt->debug(function ($type, $buffer) {
    echo "$type: $buffer";
});
