Fixed it, removed the read only attributes from cache\game\ros dir.
I also reinstalled SC but I’m not sure if this is even required, I think FiveReborn is using the one from cache\game\ros .
Now I have another problem… artifacts on top of the screen, sometimes they are from top to bottom and sometimes just a few pixels on top. Btw, tested 2 GPUs , AMD 7870 & NVIDIA GTX980Ti and the problem occurs on both.
I have no such problem in GTAO or any other game.
The crash is back, setting the compat to win8 is the only solution.
Sorry for posting this in the wrong section.
