These crashes appear to happen whenever a particular sound is triggered like an engine turning on some but not all base game vehicles and on all GM and modded vehicles. ive tested this over and over and over and cant seem to work out what exactly the file location of the crash is, all it comes up with is "Unknown Module".

Yes, ive tested a few more vehicles and get crashes when turning on the Huron (all variants), my rpt files show the error as being at a different fault address but still under "Unknown Module"

further testing shows that whenever an engine starts in the new GM vehicles or any other modded vehicle its an instant crash

Further testing is suggesting that it may be vehicle related, been trying to drive the new GM vehicles in the editor/virtual arsenal, whenever an engine starts i crash, will do some further testing with the base game vehicles
