Runtime/Managers/Implementations/UIEventManager.cs

                 im.enabled = true;
 #endif
 
-#if ENABLE_INPUT_SYSTEM
+#if ENABLE_INPUT_SYSTEM && !ENABLE_LEGACY_INPUT_MANAGER
             if (!TryGetComponent(out InputSystemUIInputModule ism))
                 Debug.LogWarning("You are using the new Input System but the UI Event Manager prefab is not configured to use input from this package. In order to fix the issue, please add and configure a InputSystemUIInputModule component to your Assets/Resources/UIEventManagerPrefab. If the prefab is not present, use the Gameplay Ingredients Wizard located at Window/Gameplay Ingredients/Setup Wizard");
