Describe the bug
Upon Selecting a video to annotate, PoseData annotator crashes with the error:

failed to demangle superclass of VideoPlayerView from mangled name 'So12AVPlayerViewC': unknown error
Abort trap: 6

To Reproduce
Steps to reproduce the behavior:

1 Open app
2 Select a video to annotate
3 Crash

Using a .mp4 does not seem to mitigate, no matter the codec.

Expected behavior
Literally, anything else.

If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):
14.4 Big Sur
15 inch MBP 2017 2.9GHz i7 16MB, 2TB

Additional context
I'm not a developer. I downloaded the Mac App store version, did not compile myself, but I do have Xcode 12 installed. I googled the error showing up in console. Maybe this will help fix: https://swiftui-lab.com/videoplayer-bug/
