    Hello..

    My project UI elements suddenly are gone and i get this type of errors:

    Code (CSharp):
    1.  error CS0234: The type or namespace name 'UI' does not exist in the namespace 'UnityEngine' (are you missing an assembly reference?)
    error CS0234: The type or namespace name 'UI' does not exist in the namespace 'UnityEngine' (are you missing an assembly reference?)

    I allready tried:
    • Resarting Computer / Restarting Unity
    • Deleting Library folder
    • Coping UnityEngine.Ui DLL to Library\ScriptAssemblies (It allways get deleted)
    • Removing Unity.UI and Re-Instaling in Package Manager
    And i cant get the problem solved.

    When i start a new project, the UI elements works.

    Assets > Reimport All

    This solves the issue but no idea what causes the issue and it's time consuming (in case of big project).
