Question Why does Intercept Vulkan vkCreateInstance crash

    I cloned the NativeRenderingPlugin project from GitHub, modified the #define SUPPORT_VULKAN 0 to 1 in PlatformBase.h file, compiled RenderingPlugin.dll based on Vulkan SDK 1.3 in Visual Studio 2022 Community, and set the dll file to load on startup in the Unity project. However, every time I open the project it crashes. After multiple tests, I found that it always crashes when executing Hook_vkCreateInstance() function in RenderAPI_Vulkan.cpp, even after switching to different Unity versions.

    When checking the Editor.log file, the log for Unity 2022.3 is

    I hope to customize vkCreateinstance and vkCreateDevice. How can I solve the crash issue?

    I met the same problem when I set the NativeRenderPlugin to preload. I have the same requirement to customize vkCreateinstance and vkCreateDevice. And I try to enable Validation layer in VkInstanceCreateInfo when calling vkCreateinstance but nothing written.
