Exporting Video from Insta360 Studio gives black output

This is weird, and I sent a email to support but never heard back, but in the 360 studio app I have my .insv files and I set up custom camera motion on them, and I want to export it to a movie. But, the first like 2 minutes of the video is black (starts with picture, goes black but still has sound, then goes back to picture)...I can play it back in 360 studio just fine. I am on a Mac and updated to the latest version of Studio, not sure what else I can do (it is driving me insane)...any help is appreciated!
