A regression since 7b4bdcd68e1e0abfab21a8be81789531d649c1ff.
Nevetheless, the file is likely broken (has non-unique metadata set UIDs), and it only worked previously because the commit changed the order of finding a metadata set based on an instance UID.
Still, regressions are bad, so I sent a patch series which should fix this:
https://patchwork.ffmpeg.org/project/ffmpeg/list/?series=10800
Can you please test? I am not sure if I managed to download the file without corruption, because the archive.org source is quite slow here...

Fixed in 68f2b32ef2b29aa95488531b007adde92ca82165.
The file is likely valid after all, see reasoning in the commit message.
Note:
See TracTickets
for help on using tickets.
I've found that this is a regression.
In ffmpeg 4.4.4, the streams are identified:
