I have the same error, I have been trying to even rebuild the entire machine and still nothing, the weird part is that happens completely random, I had several projects with RHI default in Vulkan they were opening fine, once the error happens all the vulkan projects won’t open and I will get that message. Only way to open the project is to switch back to DX12 which is a palliative solution, as we really need to see the vulkan shaders. I have been trying to look online for answers but there is nothing substantial on how to address this issue
