Upgrading to Unity 6 'UnityEngine, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'.

recently the I have upgraded the project to unity 6000 in order to take advantage of webGPU but when building the project I get many errors for DoTween as follows:

C:\Work\Projects\TCGWorldSpecialEvents\ExternalPackages\com.demigiant.dotween\Modules\DOTweenModuleUnityVersion.cs(194,62): error CS0012: The type 'RectOffset' is defined in an assembly that is not referenced. You must add a reference to assembly 'UnityEngine, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'.

PS: when building to Standalone no issues come up at all.
