Any location I enter into is totally black

Platform: Windows 10

Do you have any mods? No

Please explain the issue is in as much detail as possible:

First the icons to exit maps started to disappear but I could bypass it by saving and reloading.

But now any location I enter beside maybe the crusader camp is totally black. All of them, random encounters too. Reloading the map does nothing.

I checked games files inegrity and it seems to work again
