The message means what it says: your cost variable Cost is not
instantiated at the end of labeling.

Remove the minimize, and try running your program just with labeling:
You see that at the end your Cost variable looks like _14253{[4, 5]}.
Why?  Because the U variables, from which the cost is computed, are
not instantiated.  You have to label them as well.
