2 months ago I had the same problem.
It was caused on my system due to my regional settings using a comma (dutch regional settings) instead of a point (english regional settings) as the decimal separator.
This will crash the program, when it parses the output of yt-dlp.exe, as that always uses a point.
It is fixed in my pull request #147
I just downloaded the automatic installer and tried using YT-DLP gui but every time I start a download, it closes after a clouple seconds, leaving me with 3/4 uncompleted files in YT-DLP's directory.
