same problem, i have i5 6500 and rx 480, i think problem is rx480 anyway my solution.
1. Reinstall Origin and in AppData and ProgramData remove origin folders. Maybe You must in Control Panel set "show hidden folders and files"
2. Go to SERVICES Find and change service: Origin Client Service and EasyAntiCheat - PROPORTIES - RECOVERY set every failure "restart the service"
3. turn off GameDVR:
HKEY_CURRENT_USER/System/GameConfigStore/Right click and modify GameDVR_Enabled to 0
HKEY_LOCAL_MACHINE/SOFTWARE/Policies/Microsoft/Windows/(Create folder "GameDVR" without quotes)/(Inside the folder create a new D_WORD called "AllowgameDVR" no quotes and set it to 0"
4. set origin and apex game "run as administrator"
5. I turn off "origin in game" in origin options and every game in origin.
