There are 2 event systems in the scene. Please ensure there is always exactly one event system in the scene
UnityEngine.EventSystems.EventSystem:Update () (at C:/Program Files/Unity/Hub/Editor/2020.3.0f1/Editor/Data/Resources/PackageManager/BuiltInPackages/com.unity.ugui/Runtime/EventSystem/EventSystem.cs:398)
I have these two errors about 2 audio listeners and 2 events in the scene. They are causing my scenes to be combined when press a button in game mode. How do i fix them?
You need to make sure when you load multiple scenes at once that both scenes don’t have audio listeners, cameras, and event systems in them, or that you destroy/disable all but one.
