Thanks. I just noticed something. The game crashes even if I launch it in its original state right after installation without changing any files. So the widescreen customization is not the cause. I have also tried your linked ubi.ini along with changing to Vulkan but no avail. Installing nGlide 2.10 and trying out every possible compatibility mode for the.exe file also doesn't help.
It seems that Windows 10 itself is the cause of the crashing for some reason. What Windows 10 build do you have?
