Unable to install Microsoft Entity Framework Core for a web application

These are the errors I get when I try to install the package Microsoft.EntityFrameworkCore:

Error Code

It's a completely new ASP.NET Core 8 project, I haven't written any code yet.

I tried to reinstall Visual Studio 2022, to use the newest versions of NuGet, VS etc., clear the NuGet storage with

dotnet nuget locals all --clear

and verified that the Package Sources are correct.
