FC26 crashes on startup with C0000005 Access Violation on multiple PCs

 I found a workaround for the startup crash after EA AntiCheat.

Full credit for the solution goes to this post:

IMPORTANT:
Before doing anything, make a backup of your original folder (for example by renaming it to “EA SPORTS FC 26 - old”), since it contains your careers, profiles, settings, etc.

The solution is to copy the folder:

C:\Users<user>\AppData\Local\EA SPORTS FC 26

from a friend whose game launches correctly.

If you don’t know anyone who can share the folder, you can use this one:

Steps:

1. Backup your original folder.
2. Copy the working folder into:
   C:\Users<user>\AppData\Local\
3. Launch the game.
4. If EA App asks to repair the game, you can safely do it.
5. Once the game launches correctly, close it.
6. Copy back your original folder to recover your careers, profiles, settings, etc.

In my case this completely fixed the issue after days of trying:

• Windows reinstalls,
• multiple PCs,
• AntiCheat,
• drivers,
• BIOS,
• Amazon Luna, etc.
