dotnet nuget why on non-sdk style project's assets file doesn't work

[zivkan]

NuGet Product Used

dotnet.exe

Product Version

10.0.1xx

Worked before?

8.0.1xx doesn't crash, but also doesn't find packages used by the project

Impact

It's more difficult to complete my work

Create a non-SDK style (.NET Framework) project, install a package using PackageReference, then run dotnet nuget why path\to\proejct.assets.json Some.Package but replace Some.Package with the package name that you installed (or a transitive package).
