@barnacleboi32Ok, I have been reviewing your case for quite a while, desperately skimming and scraping all across the internet for answers as well as applying my own knowledge to the situation. I have since found some more possible causes and fixes.
Possible Causes ( and their fixes ) :
1. A hacker has gotten hold of your EA account details ( if another device is accessing your account, the original device which would be your pc won't be able to run it ) - report a hacker and/or download Avast Security Browser ( it does cost money so it's entirely optional )
2. Mods and CC causing the app to crash - delete all mods and cc AND permanently delete from recycle bin
Possible Fixes:
1. Unplug / disconnect your pc
2. Clear the Windows cache
Hope this helps xx
I don't work for EA but I like to help fellow gamers 🙂
