PlayStation Game Crashed - East Coastway Ps4 While Doing "the Journey" (tsw2)

So whilst trying to complete Step 8 of the Journey on the East Coastway on PS4 (2G41 Seaford to Brighton) I have had the game crash four times in exactly the same place..

As I've approached the 40mph speed limit when heading into Lewes (where the line merges with the line from Eastbourne) about 200 yards away the game has crashed with the playstation error code CE-34878-0

Not sure what causes it, but some details that may cause it:

I thought at first it may have been a bug with low adhesion as the first two times I was braking heavy at this point, using Brake step 3 (which caused wheel slide/low adhesion) but then on my 3rd go, i approached the 40mph with no low adhesion and the game still crashed.

After Moving the game from external storage to system storage, and completely deleting the game and reinstalling everything, I still get the same crash on this service at exactly the same point, so now i'm stumped because i've tried everything - and of course until this is figured out or fixed, i can't do the ECW journey as I can't complete it!

I've used PSN's reporting system to report the crash every time.

The error code generated is

 

EDIT: The service is 2C41 the 14:52 Seaford - Brighton (not 2G41 as mentioned)

 

Edit 2: So i was able to complete the service in Timetable mode - with the weather on sunny and clear without the game crashing, so it's either an issue within the Journey game mode itself, or its an issue with the weather/low adhesion mechanics caused by the heavy rain and heavy fog.

 

final post on this... So having completed 2C41 in timetable mode, I went back to it in the journey (this time rather than clicking continue journey, I manually selected part 8 2C41 from the list) and also drove from the train from the cab view rather than the external front view and was able to complete it without the game crashing... So yeah, what an absolute ballache but i seem to have found a work around for me
