dotnet build issue with dotnet 6.0.114

I am trying to build from source with dotnet 6.0.114, but ran into the following build issue

/opt/homebrew/Cellar/dotnet@6/6.0.114/libexec/sdk/6.0.114/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.EolTargetFrameworks.targets(28,5): warning NETSDK1138: The target framework 'netcoreapp2.1' is out of support and will not receive security updates in the future.

Let me know if I need to provide more info. Thanks!

Start by reproducing the source build with dotnet 6.0.114 and inspect src/Paket/Paket.fsproj alongside the reported project.assets.json error. Determine why the restore does not contain a net6.0 target; done means the project restores and builds successfully without this error.
