I'm seeing yt-dlp error out when using the --format flag. When the same command is executed without the --format flag, the command completes without error. I don't know exactly what is being passed to the EmbedThumbnail post-processor, but that is where the error is being thrown.
I've also noticed that when I run the same command without --format, yt-dlp skips converting the thumbnail from webp to png before embedding. Webp thumbnail works perfectly fine on my system (Win10 w/ K-Lite codec pack installed).
Here's output from the same command but without the --format flag (click to show)
