Infinite Loading Screen / Spinning Circle on Launch via Steam

Platform: PC (Steam)

Launch Arguments Used: -dx12

I am getting stuck on the infinite loading screen (spinning red logo/circle) when launching Apex Legends through Steam. I am never able to reach the main lobby. The game was working previously, but now refuses to handshake with the servers.

Troubleshooting Steps Already Conducted:

I have exhaustively gone through standard network, software, and hardware troubleshooting. None of the following have resolved the issue:

Game & Engine Configuration:

• Forced DirectX 12 via Steam launch arguments (-dx12).
• Attempted running the game directly via r5apex_dx12.exe as an Administrator, bypassing the Steam UI.
• Turned off Steam Overlay and disabled Steam Cloud synchronization to rule out cloud profile corruption.

Account & Authentication:

• Unlinked and completely re-linked my Steam account to my EA Profile.
• Cleared the Steam download cache.
• Cleared the EA Background App cache using the "App Recovery" tool.

Local & Cache Files:

• Deleted the local configuration cache by wiping the Apex folder located inside %userprofile%\Saved Games\Respawn\.

Easy Anti-Cheat (EAC):

• Ran the EAC setup tool, verified, and repaired the Apex Legends installation.
• Attempted launching via the EAC protected executable (Start_Protected_Game.exe) as an Administrator.

Network Stack & Routing:

• Reset the IP/TCP stack using netsh int ip reset.
• Flushed Windows DNS cache completely via ipconfig /flushdns.
• Manually changed DNS server endpoints to Google Public DNS (8.8.8.8 / 8.8.4.4) to bypass potential ISP routing blockages.

Hardware Conflicts:

• Disconnected all non-essential USB devices (external HDDs, hubs, flash drives) to prevent EAC hardware scan loops.

Given that local cache wipes, network resets, and account re-linking have failed, I suspect this is a backend account sync lock or a specific server-side profile desynchronization tied to my EA ID. Any help from an EA Community Manager to look into my account status or force a backend refresh would be greatly appreciated.
