Error CS0234

[Alexey]

Good day
I have errors, how can I fix this?

Assets\Scripts\Controllers\GameSceneController.cs(5,19): error CS0234: The type or namespace name 'UI' does not exist in the namespace 'UnityEngine' (are you missing an assembly reference?)

Assets\Scripts\Controllers\LoginSceneController.cs(42,9): error CS0246: The type or namespace name 'Text' could not be found (are you missing a using directive or an assembly reference?)

Is it the MMO Basics example? Did you get it from the Asset Store, or from our website?
You are using Unity 2022. If you got the example from the Asset Store, it should be the right version. If instead you got it from our website recently, it is compatible with Unity 6 only.
