I'd like to say thanks for all your help. I followed the guide best I could and did this Selective loading : untick 50% of your mods, beginning by the end of your load order and test in game. Then depending on if the problem occurs again or not, increase /decrease the remaining loading mods to find the culprit. "As best as I could follow it. It seems the "Distant Heathfire Detail" and "Skyfalls" mod(s) were to mostly to blame. After disabling them and playing for around 10 minutes notably in the same particular areas I would CTD in, I have had no such issue. Thank you for the guide and all your help, I will gladly update this if another issues arises.
