At firs I want to say thatVulkan based app stopped working after installed Cuda Toolkit v.10. I didn’t update graphics driver and other components during this installation. Only cuda was installed. Later I found that my Vulkan applications stopped to work. Any idia how fix this? Please without driver reinstallation. Because it configured and works fine.
I had the same problem. It worked again after a driver clean re-install (sorry this is not an option for you).
