"NVVM compilation failed: 3" with mesh shaders

Hello everyone. I’m using one of the newest LunarG’s Vulkan SDK (v1.3.275.0) to develop my application and newest NVIDIA Game Ready driver for my GTX 1660 Ti. I want to implement mesh shading pipeline, but when I call
vkCreateGraphicsPipelines() with mesh shaders it fails and returns “VK_ERROR_UNKNOWN” with “NVVM compilation failed: 3” being printed to console. I have task + mesh shader which compiles without any error. I can provide shader and pipeline creation / device initialization code if needed. Please help.

If this repository is wrong place to ask this question, please direct me to where I can do it.
