AFAICT the issue in this thread is a crash on startup, not a crash when opening a new project. In the past, crashes opening a project are always graphics driver crashes, because that's the first time C2 creates the OpenGL context for a layout view. So if you see a crash there you probably need to update your graphics drivers or install any available system updates. Additionally if you ever have an issue with a specific C2 version, you can always install the older working version again, although this won't fix a broken graphics driver.
Since the originally reported crash on startup appears to be fixed, closing this report.
