That file looks like it's barely playable in general.
FFmpeg and MPV can't play it at all:
VLC seems to be able to, but it complains that it's not proper:
Some players are more generous in what they tolerate but the file is undoubtedly mildly corrupted.
Lemmy should not let people upload corrupted files in the first place.
