The new Steam beta introduced a new appinfo.vdf version. This appinfo.vdf V29 introduces a new binary VDF format which does not include field keys in binary VDF segments as-is. Instead, each key is represented by a 32-bit integer which needs to be mapped to an actual string using a table stored at the end of the appinfo.vdf file.
This also means the binary VDF segments in this case are no longer self-contained. The developer can parse and provide the table themselves or instead use the ValvePython/steam library which contains a function to parse appinfo.vdf files.
