Windows Mobile Mulfunction

[Jsypher]

After updating to Build 14977.100 my phone has been behaving very strange and I'm not enjoying it ,Most of my apps like WhatsApp even games like asphalt 8 are not even opening and give a black screen then collapse when they want and during this process the back button doesn't work ,I tried a soft reset and nothing worked,did a hard reset and I lost most of the windows 10 in-built apps like groove and even maps but then I managed to download them on the store tho this is unusual,
I'm using a Lumia 930 .Did a hard reset and there are no error messages

PLEASE HELP !!
