So this is happened to me, I use Lumia 620 with WP8.1 update 1.
Since last change of onedrive backup in past month, that all of WP8.1 see error can't backup app & setting and said to upgrade your software, I notice one by one app seems to crash after splash screen, first it was only the app that I rarely use, then last week I receive popup that I haven't backup for 3 weeks, so I do the backup, but then suddenly all non-native apps is become unopenable. Even Facebook, 6tag, Whatsapp, Here apps, etc. and including MSN Weather. I tried hard reset with restoring and not restoring backup but nothing can fix it, still can't open anything useful apps other than Phone, Messaging, Email, People, Calculator, Alarm, Calendar, Photos & Camera. Other than that will crash.
Did this happen to anyone or it just me?
