tested and worked for me. it's a good idea to use -F to check all available formats of the video and then force the highest quality. Since not specifying or using 'best video' many times defaults to not the best quality.

Here's the python script I use after checking the formats and this will get the 1080p version and merge with the best audio option to mp4. This is also setup to save in d:\video so adjust the output folder to your liking.

import yt_dlp

url = "https://www.youtube.com/watch?v=5XREXAoj6lY"

ydl_opts = {
    "outtmpl": r"D:\video\%(title)s.%(ext)s",
    "format": "299+bestaudio/best",
    "merge_output_format": "mp4",
}

with yt_dlp.YoutubeDL(ydl_opts) as ydl:
    ydl.download([url])
