Problem to connect VS 2019 with my SQL Server. Error: 'System.EnterpriseServices, Version=, Culture=neutral, PublicKeyToken='

I have a problem to connect with SQL Server in my project of Analysis Services Tabular.

The error is:
No se han podido guardar las modificaciones en el servidor. Error devuelto: 'OLE DB or ODBC error: [DataSource.Error] An error happened while reading data from the provider: 'No se puede cargar el archivo o ensamblado 'System.EnterpriseServices, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' ni una de sus dependencias. No se ha proporcionado el nivel de representación necesario o el nivel de representación no es válido. (Excepción de HRESULT: 0x80070542)'.

I tried run with administrator user, reinstall Visual Studio and reinstall Net Framework but nothing works for me.

Can anybody help me?

    Hi @Luis ,,

    Thanks for your replying.

    Actually, I had a same error when I created a new project that the compatibility level is SQL Server 2019 / Azure Analysis Services (1500). But run as administrator option solved my error.

    If the above method not works, please have a try with the following:

    1. Please repair your .NET Framework, restart your server and try again to see if it works.
    2. Check the folder: C:\Windows\Microsoft.NET\assembly\GAC_32\System.EnterpriseServices\v4.0_4.0.0.0__b03f5f7f11d50a3a, if it is empty, copy these two dlls: System.EnterpriseServices.dll/ System.EnterpriseServices.Wrapper.dll into this folder. If not, register those dlls again
    3. Open the CMD and run the command: sfc /scannow to scan the system file and fix some corrupted or missing file once it found.
