Very weird bug I never heard of this before but I will look into it.

I spent some more time in it and found my Avast ransomware protection to be the culprit. Like it seems it does not allow alteration to games sav files once the process was not the one who created it, which is all but the first time od starting the game.
That means you dont need to investigate time. I have to make an exclusion for Avast here. But thanks.
