For what it’s worth, I have had FAR less crashes since rolling back all updates and re-installing everything (including the launcher) from scratch. Still have a crash from time to time but at least now I can actually make progress on a project - probably once a session now compared to once every 5 minutes previously. Also I’ve noticed that my SketchUp installation has started crashing with the latest update and it’s also related to the Intel 4400 graphics & NVidia GT630M interaction. I appear to be on the latest drivers for both, so not sure what exactly the problem is.
