Trying to export project from iPad to Macbook, but it keeps saying either the fioe is corrupted or that it can't transfer an audio/video clip

I’m trying to export a project from my iPad to a MacBook, but either it says that the file is corrupted or it can’t export an audio or video clip. This is a project with multiple tiny seconds-long clips and it never identifies which clip can’t be exported over and I have no idea how to find it.

I’ve tried detaching the audio from every clip and deleting them, but when I delete them, they just show back up in the clips. I’ve also tried just deleting the one main audio that I’m using and sending that over as a separate file but that hasn’t worked either. My iPad, iPhone and MacBook all share a photo library and iCloud obviously, so I’m not sure why they can’t retrieve the clips.
