Yeah I've been getting the exact same problem; when I woke up this morning, it opened for about 10 seconds, and I was really happy, but then it crashed again. Previously, it hadn't got past the splash screen. I tried to uninstall, repair, reinstall, disable autoupdate, roll back to a previous version, but it still hasn't been working. I hope this issue is fixed soon, since clearly a lot of people are having this problem.
