FC 26 black screen on launch, account-side issue, looking for help

Hi everyone, I'm posting here hoping someone in the community has dealt with this and found a solution, because I've been stuck for over 18 days and I've run out of things to try.

The issue: when I launch FC 26 from EA App, Javelin Anticheat loads correctly, the game window opens to a black screen, and after about 10 seconds it closes by itself with no error message. EA App stays open in the background as if nothing happened. The game worked perfectly until late April, and I have over 200 hours of playtime on my account.

I've already tried every standard troubleshooting step I could find:

• Repairing the game through EA App
• Fully uninstalling and reinstalling FC 26
• Manually deleting C:\Program Files\EA\AC and reinstalling EA AntiCheat by launching FC 26 as administrator
• Reinstalling EA AntiCheat from the standalone installer
• Updating NVIDIA drivers to the latest version
• Trying older NVIDIA drivers
• Disabling NVIDIA App overlay and Discord overlay
• Closing all background apps
• Clearing Documents\EA SPORTS FC 26 entirely
• Disabling cloud saves in EA App settings
• Signing out and back in to the EA web/companion app
• Freeing up significant disk space on C:
• Running the full clean boot procedure with msconfig
• Creating a brand new Windows user profile and testing from there
• Installing/reinstalling Visual C++ Redistributables (x86 and x64)
• Checking environment variables for GAME_DATA_DIR
• Verifying Secure Boot status and TPM 2.0
• Restarting properly multiple times
• Launching as administrator

None of it made any difference. The behavior is identical every time.

The interesting part: a friend logged into his EA account on my PC, and FC 26 launched and ran perfectly fine. Same hardware, same Windows, same drivers, same setup, only the account changed and the game worked. So this clearly isn't a hardware or local issue, it's something tied to my specific account.

I'd also like to mention that this same exact issue is being reported by other users in another active thread on this forum, with very different hardware setups (one user has a 7800X3D + RTX 4090, mine is a Ryzen 5 4600 + RTX 3050), different countries, different configurations. The only common factor between us is that our specific accounts can't launch the game while other accounts can on the same machines.

About that cross-account test: I want to mention that while it has been useful as a diagnostic, it's not really practical as a repeated suggestion for every new user reporting this. FC 26 is tied to whoever purchased it, so testing with another account requires another person who already owns and has installed the game, lives close enough to help, and is comfortable sharing their login. Sharing EA credentials is also against the Terms of Service, which makes it awkward to keep recommending. I performed this test once, it confirmed the account-side nature of the problem, and I think that should be enough.

I'm attaching a video showing exactly what happens on launch, along with my latest DxDiag for reference.

If anyone here has actually managed to resolve this specific issue (not just similar-sounding ones), please share what worked. Any lead is appreciated. And if anyone from the EA team can take a look, I'd really appreciate an update on whether there's progress on the backend side.

Thanks in advance to anyone who reads this and shares any insight.
