PS4 Tsw5 - Wcml Guard Mode Crashes

Hello,
I got TSW5 on day one (UK Regional Pack and the Class 390), so far I've not been able to complete a shift on Guard Mode, I'm able to complete operations during the journey (Tickets and Baggage) but while travelling to the final stop it crashes. I've tried it in both directions but it's still happening. It's really putting me off even playing the WCML Route at all at the moment.
