Vulkan无法找到验证层

我正在关注Vulkan教程，当我尝试检查验证层支持时。当应该返回true时，该函数始终返回false。这是代码：

bool app::checkValidationLayersSupport() {
uint32_t layersCount = 0;
vkEnumerateInstanceLayerProperties(&layersCount, nullptr);

std::vector<VkLayerProperties> availableLayers(layersCount);
vkEnumerateInstanceLayerProperties(&layersCount, availableLayers.data());
std::cout << layersCount << "\n";


for (const char* layerName : validationLayers) {
    std::cout << layerName << "\n";
    for (const auto& layerProperties : availableLayers) {
        if (strcmp(layerName, layerProperties.layerName) == 0) {
            std::cout << layerProperties.layerName << std::endl;
            return true;
        }
    }
}

return false;}

validationlayers值是{“ vk_layer_khronos_validation”}（std :: vector＆lt; const＆lt; const char*＆gt;）

vkenumerateStancelayerRayerProperties vkenumerateInstancelayerProperties无法更改availablelayers的值，因此它仍然是空的

编辑：我检查了一下，第二个vkenumerateInstancelayerProperties正在初始化矢量，但所需的验证层不在其中。

修复：我重新安装了SDK

I'm following a vulkan tutorial and when i'm trying to check for validation layer support.
the function always returns false when it is supposed to return true.
this is the code:

bool app::checkValidationLayersSupport() {
uint32_t layersCount = 0;
vkEnumerateInstanceLayerProperties(&layersCount, nullptr);

std::vector<VkLayerProperties> availableLayers(layersCount);
vkEnumerateInstanceLayerProperties(&layersCount, availableLayers.data());
std::cout << layersCount << "\n";


for (const char* layerName : validationLayers) {
    std::cout << layerName << "\n";
    for (const auto& layerProperties : availableLayers) {
        if (strcmp(layerName, layerProperties.layerName) == 0) {
            std::cout << layerProperties.layerName << std::endl;
            return true;
        }
    }
}

return false;}

validationLayers value is { "VK_LAYER_KHRONOS_validation" } (std::vector<const char*>)

after vkEnumerateInstanceLayerProperties LayersCount value is 5 so i think the problem is that the second vkEnumerateInstanceLayerProperties can't change the value of availableLayers so it remains empty

edit:
I checked it and the second vkEnumerateInstanceLayerProperties is initializing the vector but the needed validation layer is not in it.

fix: i reinstalled the sdk
