Lightroom Classic v8.3 Video Publishing Broken (merging)

Windows 10, I use a plugin and originally reported the issue to the author, he suggested I try the built in export to Hard Drive publish option which I did and it still did not export video. I also found that Exporting without a publish service (to the Hard Drive) does not work either. The video's are all mp4, a mix from my phone as well as a Panasonic camera.
