Hard PC Freeze followed by "Computer is Offline" Activation Error - FC 26

Hi everyone,

I am seeking help regarding a critical issue with FC 26 on Steam.

The Problem:

Initial Phase: For the first 4 days, the game would cause my entire PC to freeze during matches, requiring a manual hardware restart.

Current Phase: After a clean reinstallation to fix the freezing, the game won't launch at all. I am stuck in an Activation loop. The EA App asks me to sign in, and then gives the error: "We've noticed your computer is currently offline" despite my internet being perfectly fine.

Troubleshooting already tried:

Cleared EA App cache (App Recovery).

Flushed DNS and reset Winsock.

Added FC 26 and EA App as Firewall/Antivirus exclusions.

Ran both Steam and EA App as Administrator.

Reinstalled both the game and the EA App.

My Specs

Platform: Steam

EA ID: djrgavi

Steam ID: 76561199274797479

I have attached screenshots of the error below. Is there a way to force the EA App to recognize my Steam license?
