Vulkan and windowed full screen not saving/freezes

Hi all,

Was wondering if I could get some help.

Recently I have been getting an issue where Vulkan is not saving as my default when I log back in so I am having to constantly change it back over.

The same applies to windowed full screen.

That in itself would not be a problem.

But everytime I go to swap them over to the desired option, my whole game freezes up and most of the time crashes.

I need windowed fullscreen for awakened trade and my game runs much smoother on Vulkan.

Please can someone advise me a fix?

Thank you for your time.
