Please provide more information on the Arduino, its firmware, how it is connected to XBee X2C pro and the LabVIEW code too.

Usually that error means another program either has control over the VISA resource (Com port in your case) or is not properly releasing the resource when it exits.
Make sure the Arduino IDE or serial monitor still running while trying to use LabVIEW.
I have seen cases where an Arduino shows up as two different Com ports in Windows, but only one works.
