10536 just stopped working all of a sudden. Did this happen to anyone else?

I had 10536 on my 830 since the build was released and today suddenly the phone rebooted and since then no apps can be launched.

I only see the splash screen and/or "loading..." before it goes back to the start screen. After locking the screen and unlocking, the screen is just black, the task switcher shows "Default Windows Lock Screen" and killing that brings me to a black screen (or endless "loading...".

Soft resets as well as taking out the battery didn't help. Time for another hard reset. :/

Did this happen to anyone else?
