May I ask, are you using officially released youtube-dl version 2021.03.25?
When I run youtube-dl with your options, I get ERROR: Only mp3 and m4a/mp4 are supported for thumbnail embedding for now., and the last 2 lines of your verbose log indicate that you are using not yet merged pull request #22659 or derived embedthumbnail.py module.

Oh yeah I used that PR for fixing the thumbnail embed not knowing that it could actually break the subtitle embedding module. My bad didn't check it the first time but using the release from this repo resulting expected error for thumbnail embedding but fixed subtitle embedding.

I'm truly sorry for that, and I'm closing this issue

Thanks for bringing that to my attention @kikuyan
