There may be rare map-specific crashes, such as crash on map 4 (rooftop) where crash might occur if you are moving too fast. If you are experiencing this particular crash: move slow or temporarily change rendering by removing a -vulkan launch parameter. The -vulkan parameter subsequently must be brought back as soon as possible once you are past the potentially problematic area. If you are experiencing this too often, remove -vulkan throughout the entire map before transitioning to it. Return to -vulkan after that, because it is essential throughout the entire playthrough. This kind of method is not recommended, it is encouraged to keep -vulkan at all times. This specific map does not require vulkan.
