MSP430FR2355: Symbol Has Already Been Defined Error

Part Number: MSP430FR2355

Hi all,

Working on one of my scripts and CCS has started giving me the error "[E0300 Symbol TI__int33 has already been defined" for specifically line 16 in my code. Previously I've had no issues with this, and then I tried commenting out the line to troubleshoot whether or not the error disappears, it doesn't. Can anyone provide me with some guidance as to what would be causing this? For context this is part of a MODBUS routine. 

Thanks in advance!!
