GP3 crashes with GPXPatch

I run GP3 with the the latest GPXPatch and everything loads up fine but after a few seconds/minutes of racing it crashes to desktop.
However the Game runs well when not using GPXPatch.
Any help gratefully accepted
Kind Regards
Using Windows 10
Asus laptop 64bitnvidia GEFORCE GTX

Never mind!
It just crashes after a few minutes racing whether I use GPXpath or just gp3.exe, so I have ditched the game completely

I decided to give it one more try
So, I just ran a full race - 60 Laps - in GPXPatch in cockpit mode only and no crashes.
It also runs without crashing using onboard car camera views
However as soon as I go to Full Exterior view .......it crashes
So if anyone please can shed any light on this?
with thanks

so, if that's happening in every circuit? or a particular one? That could depend by a bug in a track when change the camera (external). which track is it?

Have you tried with "debug mode" option set?

it will not let me run in debug mode - i get an error has occurred message
