DNT switch-to-project doesn't work with .net core 3.1 and net core 2.2 project

I just updated my VS 2019 to 16.4 and it updated net core to 3.1 automatically. when running the dnt switch-to-projects, there are a lot of errors showing.

C:\Program Files\dotnet\sdk\3.1.100\Roslyn\Microsoft.Managed.Core.targets

It works well before but after update VS, it stops working.

@RicoSuter Is this still a known issue? I have been trying to use the switcher on a .net core project and have run into some issues. I thought I would just clarify is this is an open issue still or not?

I have updated the tools to the latest version and my problems have now gone away. dotnet tool update -g dnt

last time, I tried to uninstall it and reinstall, it worked.

I'm using .NET 5 now and it's working again for me. Maybe the original issue was specific to .NET Core 3.1?
