This looks like it's been created on a mobile device. I have had
experience of a phone creating a 'truncated' file which cut off
before the actual due to a corrupt MOOV atom / extraneous 'ftyp'
The video file played correctly on the phone and on online viewers (eg
YT) but not with either VLC, ffplay, etc.
I could salvage the file by uploading to eg GDocs / YouTube and
re-downloading. You may also wish to have a look at the fork of
untrunc. Others here can advise if ffmpeg can do something useful
with your video file.

Separately, I have seen others advise not to use -hide_banner when
preparing output for questions asked of this list. It is germane to know
what version a querent is using and with which options.
