Steam Crash When Loading Into Or Passing Vectrons

Whenever I try to load into or pass Vectrons on German routes, my game crashes and I get this UE4 error:

Code:

EXCEPTION_STACK_OVERFLOW

I do not have any other evidence or report.
This results in many journeys being impossible to complete as you will often pass a Vectron at some point. It started happening recently and I can confirm it is not down to a lack of memory. I have also verified the files to no avail. Can anyone assist?
