Receiving an error related to a Unity UI menu linked to AC

Unity 2020.311f1
Ac 1.75.0

I have a Unity UI menu that's giving this error and preventing the scene from launching:

NullReferenceException: Object reference not set to an instance of an object

Relevant images:

Everything was working when I had only 2 of the buttons linked. The issue started when I went and linked all the 12 elements.

Any ideas what it could be?

12 elements as in 12 separate Interaction elements?

As a test, open up AC's MenuInteraction.cs script, and look for the following around line 121:

uiSlots = new UISlot[_element.uiSlots.Length];

Replace it with:

uiSlots = (_element.uiSlots != null) ? new UISlot[_element.uiSlots.Length] : new UISlot[0];

Does that resolve it?

Thanks, that worked!
