After this ffmpeg just close and output.mp4 is empty.

-ss 00:00:03 - this is just for example, you can take 5-10-40 seconds. It also appears on other MPEG-TS with VVC files.

The same behavior in third-party applications that use ffmpeg for decoding, for example in ​https://github.com/Aleksoid1978/MPC-BE

The mentioned sample was taken from this page:

There is a peculiarity of downloading. After the first click Download will ask for e-mail, you can ignore it, when you ask again, it gives download.

The crash is resolved by 5076fa30ab6f36955dc711f348a16fd063c1e962. The file still fails to decode however.
