I\'ve been given a visual studio 2017 solution. When I open it fails as with the error:

You will encounter the same issue in Visual Studio 2019. I have the same issue, I thought it was a conflict on Visual Studio 2017 but it wasn't.
The fix is you have to remove the source that is causing the issue.
You can remove it via Tools -> NuGet Package Manager -> Package Manager Settings
Tools
NuGet Package Manager
Package Manager Settings
