An attempt at Vulkan

I need some help.

When I open the validation layer of lwjgl-vulkan, this problem occurs.

    36. public class ColoredRotatingQuadDemo {


    37.     private static boolean debug = System.getProperty("NDEBUG") == null;


    38.

    39.     private static String[] layers = {


    40. 			"VK_LAYER_LUNARG_standard_validation",


    41. 			"VK_LAYER_KHRONOS_validation",


    42.     };

    44.     /**

If anyone is willing to help, please try running this demo and enable the validation layer to see if it also triggers a null pointer crash.

I tried to run the compiled shader, but it seems the shader returned an error code -4 and exited. I’m not sure what -4 means. I need to enable the Vulkan validation layer to locate the issue, but when I turn on the validation layer, the program triggers this null pointer error.
