2. An AssetDatabase Refresh is pending after a successful Package Manager request. You should not call AssetDatabase.Refresh at this time because it can lead to import-related errors.

Somehow, I just solved it. Steps:

1. Open Unity Editor and create a new empty 3D project;
2. Open Asset Store (at the center of Unity Editor) tab, and open Karting Microgame asset in it;
3. Download and import Karting Microgame through this Asset Store tab within Unity Editor;
4. And, while importing, Unity Editor will pop up a window saying wether to update/install a package or not, choose "update/install";
5. All done! The game is ready to go~

The point is: avoid using Unity Hub for importing!
