Nuget The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding char

According to the error message, it seems that there is a syntax error in the nuget.config file.

So, to resolve this issue, please try to close all Visual Studio instance, delete the nuget.config file in the path C:\Users\<Username>\AppData\Roaming\NuGet\nuget.config. Then reopen the Visual Studio, Visual Studio/nuget will regenerate it.

Hope this helps.
