Video (MP4) doesn't work on MacOS desktop client

This video loads a preview on the desktop MacOS client.
However, click on the play button and it doesn't ever play.
It also doesn't play if pasted onto onto another discord server.
It doesn't play if I restart the desktop client.

Version:
0.0.264 (0.0.264)

Video works fine if I open it in a browser:
