PublishWorkshopFile failed! (8)
This error happens when the addon.json contains invalid UTF-8 sequences. This happens if you use an upload script (.cmd, .bat, etc) that cannot create the addon.json with the UTF-8 character set. Please fix your addon.json by editing it as UTF-8 or use a title using only US-ASCII characters (latin characters with no accents). This error only happens after the upload because the addon.json is packed inside of the sent GMA file.

it may be coincidental but when I got the steam beta for the new UI, it prevented me from uploading to the workshop
