SevenZipSharp library not working on Xamarin forms

Question

We are working on a Xamarin project that needs to split a large file into smaller files with specified file sizes. we tried to use the SeveZipSharp library by installing the squid-box-sevenzipsharp NuGet package which supports xamarin forms for compressing and decompressing large files.
But while we compress the large files, we got an exception: kernel32.dll assembly:<unknown assembly> type:<unknown type> member:(null) 
For your reference, this is our code,
 try
            {
                string dll = @"/Users/macmini3/Documents/7z/7z.dll";
                string filename = @"/Users/macmini3/Documents/FileFolder";
                string output = @"/Users/macmini3/Documents/Files/zipped.7z";
               
                SevenZipCompressor.SetLibraryPath(dll);
                SevenZipCompressor compressor = new SevenZipCompressor();
                compressor.ArchiveFormat = OutArchiveFormat.SevenZip;
                compressor.TempFolderPath = Path.GetTempPath();
                compressor.CompressionMode = CompressionMode.Create;
               // compressor.CompressionLevel = CompressionLevel.Fast;
                //compressor.CompressionMethod = CompressionMethod.Lzma2;
                //compressor.ZipEncryptionMethod = ZipEncryptionMethod.Aes256;
                compressor.VolumeSize = 5000000;
                var assemblyDllPath = compressor.TempFolderPath + "32-7z.dll";
                //var assemblyDllPath = compressor.TempFolderPath + "64-7z.dll";
                File.Copy(dll, assemblyDllPath, overwrite: true);
              //  SevenZipExtractor.SetLibraryPath(dll);

                compressor.CompressDirectory(filename, output);
            }
            catch (Exception ex)
            {
              // throws an exception, Kernel32.dll assembly:<unknown assembly> type:<unknown type> member:(null)
            }
We are using Visual Studio Community 2019 for mac (Version: 8.10.25) and Xamarin Forms (Version: 4.5.0.356)

1. Can anyone please help us to resolve this issue?
2. Does the SevenZipSharp library support the Xamarin Forms project?
3. Can anyone suggest any other thirty-party library (Paid/Free) to split large files into smaller files that support Xamarin Forms?
