Answer:
This error tells you that there is a version conflict detected. It goes on to show you where exactly is that error. It'>#bfedd2;">It is most likely that you have unknown version number in one of your package references in the csproj file.

In this case the package that had a wrong version was Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation of version 5.0.1 looking around there is no build with the version 5.0.1. Therefore, downgrading the version number to 5.0.0 fixes the issue.

  <PackageReference Include="Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation" Version="5.0.0" />
