i think the repro is this:
create an action A1
add an event in the player input to A1
then delete that action A1
and press play
Cannot find action ‘gameplay/camera dolly in[/XInputControllerWindows/rightShoulder]’ with ID ‘47c05baf-3bac-43d0-b1b2-50f12ad3e14f’ in 'MC_Input (UnityEngine.InputSystem.InputActionAsset)
UnityEngine.InputSystem.PlayerInput:OnEnable() (at Library/PackageCache/com.unity.inputsystem@1.1.0-preview.3/InputSystem/Plugins/PlayerInput/PlayerInput.cs:1581)
expected = no error, the event is simply removed
