Ec:10001,Ec:10005, black screen. stuck on loading screen in the launcher

1.when i enter EA app it shows black screen and network errors like ec10001, ec10005 and "you have problem with your EA account.

2.after using vpn it works and lets me log in and if i press sims 4 then the game doesn't launch...its stuck on a launching loop

2.5--i also chatted with multiple support advisors and followed instructions from them. i think its completely EA's fault in there servers or the system. because i and people only have problem with EA app, also i dont wanna use the ea app and open sims 4 from epic ....how can i do that?

3.i have tried many things to fix this sims 4 loading problem but nothing works. i already did these troubleshooting steps:
i change my internet network and mobile data to enter the app because of black screen.
i moved my mods folder to desktop and delete all cache files but game still loading.
i try to play in offline mode but the sims 4 wont launch at all.
i forced close all background apps and ea app from task manager.
i use the app recovery tool and repair the game from the library.
i also try to run the ea app as administrator and reinstall everything.
i try to use vpn and change dns settings but still same problem.
i try to log out and log in many times but the ea app keeps looping. 
 i know people have these problems like ec10001 and ec10005 for 3+ years in the forms . i see people fixing it with random clicks or vpn but for me nothing is working for me. the ea app keeps looping the launch and saying "there's a problem with your account". i just want to play my sims 4 always offline without these issues. how can i fix this loading loop now?

4.Since the standard troubleshooting steps didn't work, I would like you to perform a manual verification of my account entitlements. Please check my Sims 4 game license and offline play permissions on the back-end. I believe there is a sync issue or a digital signature error (like EC10001) that is preventing the EA App from validating my account for offline use. Can you please refresh my account permissions manually so I can stop the loading loop and play offline?
