The kind of process failure that has occurred. This is a combination of process kind (for example, browser, renderer, gpu) and failure (exit, unresponsiveness). Renderer processes are further divided in main frame_ renderer (RenderProcessExited, RenderProcessUnresponsive) and _subframe_ renderer (FrameRenderProcessExited). To learn about the conditions under which each failure kind occurs, see COREWEBVIEW2_PROCESS_FAILED_KIND.
