Argument Null exception

[Beqo77]

When I enter the play mode or exit the play mode some connections gives ArgumentNullException. When I enter the playback mode, it sometimes gives 5 connection errors, sometimes 0.
In my scene, I have multiple  disabled levels with active multiple level connections .

I am using curvy 8.5.0.
Unity version 2022.2.12

Exception:

ArgumentNullException: Value cannot be null.
Parameter name: identifier
UnityEditor.Undo.RegisterCompleteObjectUndo (UnityEngine.Object[] objectsToUndo, System.String name) (at <ae93fefe62eb49e6b9ef3807ffd33dc7>:0)
