Bug Unity instance missing in "Attach Unity Debugger"

When I click on "Attach Unity Debugger" in VS 2017 the list is empty!
This https://answers.unity.com/questions/817612/unity-instance-missing-in-attach-unity-debugger-vi.html don't work: doesn't exist "Visual Studio Tools".
This happens from Unity 2020 LTS.

 

You might want to check some of the usual stuff for fixing intellisense, as it might fix the debugger attach too.

This may help you with intellisense problems:
