I just upgraded to Unity 2020.1.0f1, and unfortunately it broke the Immediate Window package (version 1.1.0-preview.3) with this error message:

[CompilerError] The type or namespace name 'UnityScript' could not be found (are you missing a using directive or an assembly reference?)
Compiler Error at Library/PackageCache/com.unity.immediate-window@1.1.0-preview.3/Editor/Sources/UI/Window/Console/OutputItem.cs:2 column 7
1:   using UnityEngine.UIElements;
-->2:   using UnityScript.Scripting;
3:   using UnityEditor.ImmediateWindow.Services;
4:   using UnityEngine;

There’s no workaround, the only option is to uninstall it.

I just tried looking for the package to install it on 2020.2.2f1 and it’s not in the package list.
