I have an Impress presentation that includes an embedded video on slide 2. It has been working under Apache OpenOffice 4.1.6 and Mac OS X 10.14.4 until yesterday. Since then, when trying to open the presentation it loads the first page, but on trying to get the thumbnail for the second page, the whole application crashes. I have tried going back to previous versions of the presentation with time machine, but there has been embedded video on that slide from the beginning.
a) is there some way around this?
b) is there a way to open the presentation in a different program to delete the embedded video and then start using it again in Impress?
I can attach the file here, if that would be helpful.
