One possible reason could be that the zstd library was compiled with a 32-bit architecture, which has a maximum file size limit of 4 GB. To decompress files larger than 4 GB, the zstd library needs to be compiled with a 64-bit architecture. Another reason could be that the operating system itself has limitations on handling files larger than 4 GB, which can affect the zstd library's ability to decompress such files.
