*Steps to reproduce:*
# Create a new 2D URP project in 6000.2.0a5
# In Package Manager, install 2D Animation samples
# Open the scene inside the sample's "Assets/Samples/2D Animation/10.2.0/Samples/3 Character/_Character.unity" or "Assets/Samples/2D Animation/10.1.4/Samples/Extras/Attachment Points/_Attachment Points.unity" and go into Playmode

*Actual results:* 
Errors are being displayed such as the following
{noformat}
InvalidOperationException: You are trying to read Input using the UnityEngine.Input class, but you have switched active Input handling to Input System package in Player Settings.
UnityEngine.Input.get_mousePosition () (at <a00997cada454d618ca56426f89409b7>:0)
UnityEngine.EventSystems.BaseInput.get_mousePosition () (at ./Library/PackageCache/com.unity.ugui@50015aa2fc19/Runtime/UGUI/EventSystem/InputModules/BaseInput.cs:75)
UnityEngine.EventSystems.StandaloneInputModule.UpdateModule () (at ./Library/PackageCache/com.unity.ugui@50015aa2fc19/Runtime/UGUI/EventSystem/InputModules/StandaloneInputModule.cs:180)
UnityEngine.EventSystems.EventSystem.TickModules () (at ./Library/PackageCache/com.unity.ugui@50015aa2fc19/Runtime/UGUI/EventSystem/EventSystem.cs:481)
UnityEngine.EventSystems.EventSystem.Update () (at ./Library/PackageCache/com.unity.ugui@50015aa2fc19/Runtime/UGUI/EventSystem/EventSystem.cs:496){noformat}
 

*Expected results:* No errors should be displayed

*Reproducible with versions:* 2D Animation 10.1.4 / 2D Animation 10.2.0

*Not reproducible with versions:* 

*Can't test with versions:* 

*Tested on (OS):* MacOS

*Notes:*
* No functionality loss is observed, sample scenes is still working as intended
* This is most likely due to the update of the input handling changes in the `activeInputHandler` inside the "Project Settings -> Player" being set to "Input System Package (New)
* Happens on 6000.1 and 6000.2 2D URP templates
* This also happens on the Scene "Assets/Samples/2D Animation/10.1.4/Samples/Extras/Attachment Points/_Attachment Points.unity"
* {{In the EventSystem}} gameobject and clicked on {{Replace with InputSystemUiInputModule}}  inside the Standalone Input Module component, the error cease to appear
