https://github.com/dotnet/runtime/issues/36590#issuecomment-689883856 referance this modify CreateAndCompileToStream

  CSharpCompilation compilation = CSharpCompilation.Create(
                fileName,
                new[]
                {
                    syntaxTree
                },
                options.ReferencedAssemblies
                    .Select(ass =>
                    { 
                        unsafe
                        {
                            ass.TryGetRawMetadata(out byte* blob, out int length);
                            var moduleMetadata = ModuleMetadata.CreateFromMetadata((IntPtr)blob, length);
                            var assemblyMetadata = AssemblyMetadata.Create(moduleMetadata);
                            var metadataReference = assemblyMetadata.GetReference();
                            return metadataReference;
                        } 
                        // return  MetadataReference.CreateFromFile(ass.Location); 
                    })
                    .Concat(options.MetadataReferences)
                    .ToList(),
                new CSharpCompilationOptions(OutputKind.DynamicallyLinkedLibrary));

it’s worked
