I am trying to publish a SL 360 course as a video (mp4) and it will not complete. I have 6 slides, and on one slide is a 90-second video. The total time for all six slides is about 2 min, 16 seconds. It has been publishing now for almost an hour. The message reads "Encoding Video - 1.6 Untitled Slide - 2:16." So it appears to have gone all the way through based on the time, but it will not finish. I have tried this three times and it gets stuck right here. I even tried removing the video from my project and it is doing the same thing - any ideas? Thank you.
