Nuget Package issue

<ErrorText>This project references NuGet package(s) that are missing on this computer. Use NuGet Package Restore to download them.  For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is {0}.</ErrorText>

I have tried automatic restore, I have also added these packages manually but nothing happens. I am using visual studio 2019, on MACOS Big Sur
