After upgrade to WP 10 anniversary some apps won't launch

[Windows Central Question]

I have a Lumia 640 and have upgraded to the Anniversary update, a lot of apps won't launch, Discovery News, Network Speed Test, Microsoft Authenticator, Litecoin easy check, etc. Even Settings! They immediately close.

I have tried to download to re-install say Network Speed test, but it is stuck at "working" and rebooted a couple times.

Would you recommend waiting for an update? Resetting the phone and starting from scratch or resetting the phone and restoring a backup?

Or is there something else that could fix this?

Hard reset is more preferable. Update may not fix the issue

do a factory reset and then no restore
