Astral Sourcery 1.16.5 Korean version has been translated. I can't guarantee the perfect quality, but there were no problems when I played it.
I'm still inexperienced in using github, so I don't know if I can upload files or not, so I'll just leave a link to Google Drive.
I hope I can be of some help.
