Since upgrading, exporting a Gif, PNG or video just sits on the export screen. Nothing happens even after waiting quite a while. It was typically less than a minute and showed the preview of the frames as it was exporting.
There is an issue where Hype appears to hang at the end of the export process, but I haven't seen this particular issue.
Could you submit an issue from within Hype, using Help > Report an Issue and include your logs and document?
