Hi Amanda L Court
Welcome to Microsoft Community.
I realize that you've encountered a problem with " PowerPoint Export Issue ", and I understand how you feel. Don't worry, I'll do my best to help you.
After receiving your question, I went to PowerPoint to test it. I can export it as a video normally. If possible, can you provide your PowerPoint version and your operation steps? Did you export it directly as a video or recorded it through "Highlights"? I hope you can upload a few pictures or videos to let me better understand your problem, which will help me better help you.
In addition, have you tried to export other PowerPoint files? This can help us find out whether it is a problem with individual files or applications.
Looking forward to your reply!
Best regards
