This is likely related to the issue that caused app icons to become corrupted or change names. I've had a couple of apps (advanced task manager, for one) that exhibit this behavior often, and simply refuse to run afterward.
I'm hoping that the bugfix release will patch this issue, as it appears to be related to corrupted cache files on the phone, unfortunately we're stuck with this behavior until then. Sorry to hear it's so severe for you, that's usually not the case.
