Not a new crash since I could find crashes with the same stack going back all the way to ESR68. This is a simple NULL-pointer dereference. We're not checking the HRESULT value returned by IDWriteFactory::CreateRenderingParams() before accessing the pointer it returns so we're probably getting a NULL pointer there.
