Ah, interesting. The Stall detector exceeding a budget of 2 seconds suggests that the shader compilation process is taking longer than it should. The Crash inside the platform compiler! message also indicates an internal failure. So, there could be a couple of reasons for this…
You should definitely verify if you need to update your graphics drivers (perhaps try a clean install). Also, ensure that the DirectX Shader Compiler (DXC) is correctly installed and configured (it should be from the get-go, but who knows, maybe something on your system messed with it?).
You could try increasing the shader compilation timeout in the engine settings. This might allow more time for the shaders to compile without triggering a crash, although it’s more of a workaround than a solution to the underlying problem…
Maybe try these things and let us know how it goes!
