It's more difficult to complete my work

Repro Steps & Context

This command fails to restore all the nugets to C:\Users.nuget\packages.

dotnet restore MySolution.sln

Using NET 8.0.400.

This behaviour doesn't occur in all situations, so I've added a solution where it's easily reproducable.

Restoring nugets for the solution (in Visual Studio, or on the command line with dotnet restore) will seemingly randomly restore the nugets from one of the projects, but not for the other. Illustration added.
