VSCode dotnet 3.0 attach debugger not working

I just upgraded my whole project to dotnet 3.0 (aspnetCore3.0 and EFCore3.0). Before the upgrade, in VS Code I could attach to the dotnet process and debug just fine.

Now, it asks me to pick the process like it did before, but when I do, the debugger doesn't work. It's not loading any symbols.

I am using this command to run the app in the terminal:

dotnet run --project myproj.Web/MyProj.Web.csproj --environment "Development" --server.urls "http://*:5200;https://*:5201;"
