Animator "Not initialized" when copied to another PC

Unity Engine
1

I have a prefab setup that contains the UI for my scene.

On my work PC I created animations for some arrows that move and scale over time.
After moving the prefab to my personal PC (Tried both perforce and moving the files over my network directly) the “Not Initialized” message appears.

If I go back to my work PC the Animator says:
Clip Count: 1
Scale: 1
Generic: 1
Curves Count: 4
Stream: 4
Everything Else: 0

But after moving the prefabs and all needed files to any other PC the Animator says:
Not Initialized

I have the Animation Controller and Animation which I can see copied correctly as far as I know.
Is there an extra step I have to take when adding an animation to a UI element that is part of a prefab?

Also:
The Prefab instantiates without errors and on my work PC the animations play while any other PC I copy to does not have an animation playing at run time even though they are present and I get no errors.
