Thank you for information about similar problem.

This problem is observed and reported on 7-zip library project, https://github.com/miurahr/py7zr/issues/178.
py7zr heavily depend on lzma FORMAT_RAW interface.

Fortunately  7-zip container format has size database, then library can know output is enough or not.

In reported case, the library/caller become a state that all input data has send into decompressor,  but decompressor does not output anything.

I'd like to wait upstream reaction.
